Can't log on to MS Exchange Server

What's going on? Does it not recognize your login?

You might try going into Control Panel, Mail, click on Show Profiles, and remove your Exchange profile, then rebuild it. You just need to know the name of your Exchange server, and your email name.

This will only create your Exchange Server and Outlook Address Book services. If you had Personal Folders and Personal Address Book, you have to re-add the service on the Tools, Services menu, and point them to your old files.

I have seen things similar to this - you may wish to double check your WINS settings - try and "ping" the exchange server name from your workstation.

try deleting any .pwl files that are on your computer. Your computer may have a corrupt password file that is causing the problem..

Is your network login name different from that of your email alias? I mean, is your net login name jsmith, but your email is johns??

In your outlook settings, make sure your loing name is \\domain\\netlogin\\mailbox alias and see if that helps.

See my comment after Answer 4 for more info.
Thanks!

When you ping the Exchange box, are you using the IP address or the server name? Are you logging into an NT/W2K domain before you launch Outlook? Does that work? Try substituting the IP address of the Exchange server for the WINS name in the Outlookprofile.

Try setting the "Logon Network Security" setting to "None". Outlook->Tools->Services->MS Exchange Server->Properties->Advanced. This will make Outlook ask you for logon credentials: username, password, domain; when you launch it.

couple more questions: Are you using the corporate\workgroup version of Outlook, or Internet Only? To check, go to Tools | Options | Mail Services and click on Reconfigure Mail Support to see which it is now. Just cancel out to avoid changing it.

Anything at all that you know of that changed on your end when this ocurred?

This may seem "ridiculous" but, since you've attested good health & configs of your account, connetivity, client/server connectivity settings... Check:
(1) Language/Encryption settings on your box.
(2) Any recent changes (any!) to server configuration.
(3) Has anyone in tech support started using or 'playing with' any tool that offers them a single interface to the many separate NT admin tools? (Some of them wreak havoc with permission settings and database synchonization between servers).
(2) Possible aftermath of a defunct intrusion or infection, like (e.g., Code or garbage attaching to every transmission stream from you but that happens to be in a place that, so far, only interferes with what Exchange is looking for.
(3)Is the computer connecting by dial-up or LAN connection?:
- Corrupt MAPI client (if you're using that),
- MAPI conflict with other dial-up apps or web app agents that stay live, both potentially streaming garbage with your transmission
- Any internet certificates installed on your computer/
(4) Remove addressbook services and work with tech support to bypass addressbooks and related config files on your machine.
(5) Find out when the last time tech support ran ISINTEG to check integrityof Information Stores.
Time for bed...more soon.

What OS are you using? What did they change? IP addresses on any of the servers, routers, etc? You may not know, and they may not admit to anything. This happened to me two months ago.

Sorry to leave two messages, but.. Do you know what OS is being run on the exchange server? Is it a single or multiple domain network? Has anyone rebuilt the account on the exchange server? Is the domain controller and the exchange server running the same OS? Thanks

Normally the "Logon Network Security" settings in Services->Exchange Exchange Server->Properties->Advanced should be set to NT Password Auth. Usually if it's set to None, you'll get prompted to enter your NT logon credentials.

What OS are the machines running where you can access your exchange account? Do you know someone running XP where you could build a profile and try their machine?

You said your authintication was set to none. How are you logged on to XP? If you are logged on as administrator, you may need to create an account on the PC that matches the mailbox user ID you have. Your PC may be trying to logon automatically as administrator with exchange. Also make sure that there is not a workstation account on the domain that matches your workstation name. If there is, and the SID is wrong, that could prevent authentication. Also kerberos requires that the time on your PC be within 5 MINUTES!! of the time of the server that you are logging into.

have your Exchange admins check the "Primary Windows NT Account" associated with your Mailbox on the server.

MMMMMMMMMMMMMMMM..........
Looks Like Thats A HArd one
ok
ummm try going into the regedit and set @shell32.dll,-22053 to RegSZ Outlook Express Its either
0x0000000 or 0x0000001 try both make sure you backup the reg if ya not using xp by scanreg scanregw
goodluck buddy

What is the error message???
Apparently you have a corruption in Outlook on that machine.
Are you sure you do not have a virus on that computer.
Check your windows .ini file.
You may want to repair the install of Outlook.
You can check the mail configuration in the control panel. Ensure that it is correct. And no others are configured.

WoW ! this is a bit of a book!!

Ok. Iappriciate you position.
Ask the techie on your support desk to log on to the exchange box ask service administrator and
have a look to see if your profile if still intact and valid. if not then they will have to either restor the dbase (Not likely) or create another for you and transfare it to your noew profile.

Good luck

I'm having the exact same issue with a windows 2k machine loggin into the exchange 5.5. Please email with a solution and I will do you the same if I find one first!!! I have even applied the pre released sp3 for windows 2k with no avail. I will let you know!!

Here are a couple of things to try:

----------

Locate the following registry key:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\control\LSA\LMCompatibilityLevel

Change the value to 2.

If the value IS set at 2, change it to 0. You mayhave to coordinate with the mail administrator with this, but the possible values are:

0 - Send LM and Windows NT authentication (default).

1 - Send Windows NT authentication and LM authentication only if the server requests it.

2 - Never send LM authentication.

----------

Does your user name have any unusual characters in it?

Try changing your user name to something that contains only letters.

----------

Those are a couple of things to consider.

Good luck,

Maxwell

Sounds like you might have a DNS issue. The first server name they are providing you with is mostly likely a Global Catalog Server, while the second is your Exchange Server. The name they gave you for the Exchange Server seems to resolve against WINS, while when you put in the GC server name (which has to be resolved via DNS) isnt working. Also when you log into Outlook, (XP/2000) looks up in DNS, domain controller information. Since it seems the DNS server is wrong you cant authenticate.
So... check DNS. Both on your XP box and on a Win2k workstation that you can get into Outlook on.
Also ping by name the server name (the first one, not your Exchange Server) from both machines and see what IP is returned.
If all else fails ask tech support for the IP of Exchange and your GC and create a hosts file on your XP box.

Hi

logically we have to ask these qustion.

IF the server is up then
use network diagnostic commands
IF there is a basic network connectivity to the server then

ping the server by name to see which network address the name resolves to

IF other client has the same problem

exchange server with RRAS or RAS may had added IP address to the DNS server from sources such as ISDN lines

else
If the necessary protocols available on the network
make sure that the necessry protocols and the right ports are available from both ends
to test connection to a particular port
run Rpcping on both the client and the server
run Telnet command
endif
endif
else

use Ping and Tracert utilities to check the server's IP address

endif

else
turn it up
endif

good luck

Hi,

Perhaps you (or some piece of software) has turned on XP's firewall and is blocking port 25?

Take a look at the following article on XP's built-in firewall if you need to.

http://www.microsoft.com/windowsxp/pro/using/howto/networking/icf.asp

(remove spaces from the above URL)

Another check would be to use XP's hyper terminal and make a connection using port 25 to your exchange server - make sure you can make that connection.

Cheers,
Tim.

Okay. We are getting somewhere. Putting the IP in worked in that you are prompted for your logon credentials, when using the name you get a server could not be found. Definately DNS.
To check DNS you can from the command prompt (this works on both WinXP and Win2K)
ipconfig /all
You should find an entry that says:
DNS Servers.......
See what is listed for these servers. They should be the same. If they are different set your computers DNS to the same as the Win2k workstations.
To set DNS. Open Control Panel, then click on Network Connections. If you have the Category view on you will need to click on Network Connections again. Find your Local Area Connection and right-click to see properties. On the general tab locate the Internet Protocol (TCP/IP) select it and click properties. On the general tab, change to Use the following DNS server, and put in the ip addresses from the Win2k workstation. Click OK a couple times and give it a try.
A prosible workaround would be to create a hosts file on your computer with the ip and name of the servers in question.
In the following directory (for WinXP)
C:\windows\system32\drivers\etc
edit the file called hosts (there is no extention on this file) Add the IP and name ofthe first server. So it should look something like:
10.1.1.10 servername.domainname.edu

Ok, here's more info that may or may not help. I wrote an email to someone with an address that wasn't in my address book but I couldn't send it. When I clicked send I got the error, "Outlook does not recognize one or more names." I can send emails fine to anyone on my address book but that's it. I can't even send an email to myself.

Have you tried editing the hosts file to give the exchange server a specific IP and hostname?

Seeing as you're going through OWA, ping the server and grab it's ip address. i.e. mail.server.com

do a search for your hosts file on your workstation and edit it with notepad (careful not to associate it with notepad by not selecting always run with this program option)

pop in the server IP address and hostname by what you have as the server name in your Oultook profile for the exchange server. (Right underneath your username) Do not save the file witha txt extension.

So now when you type ping servername you get a response. So now your PC has no problems knowing where to look for the server on the internet. This should help pinpoint the problem or fix it altogether.

Failing that reinstall Outlook. But I doubt that's the prob...

Sounds like a DNS issue...

Just thought of something else. You mentioned that the IP of the server changes from time to time. Perhaps their DNS info is not propagating to your ISP properly. What you can do is perform a dig to find out which nameservers the Exchange server itself uses, then use one of theirs as a secondary for yourself. Goto http://www.zoneedit.com/lookup.html enter the server IP or canonical server name mail.server.com in the DNS box look select ALL results and then look for ns1, ns2. These are their nameservers. You can use any DNS server so you might as well grab one of theirs for your Primary, secondary or as a third?!.

Most likely your ISP could be having DNS domain issues with your Exchange server's domain.

Hope this helps...

I do not see anyone telling you to run a detect and repair on you mail program.. Outlook 2000 Is likely the Problem.

Hi,

Regarding your latest comment on this problem : I assume you did that from another machine? You were saying that you could use Outlook from other machines but not your own...

I guess that puts the problem back on the server.

Do you have"keep sent messages" turned on?
Turn it off and try.

Do you have enough space on the server?
Probably otherwise you wouldn't be receiveing any mail...

Can you add addresses to your address book and then mail to them?
You may have a corrupted address book.

A few more things to look at, anyway...

Cheers,
Tim.

The error message you are getting implies that your username and password are not correct.

Maybe try the following (in this order):

Set your windows XP username and password exactly the same as your email account username and password (not your email address). try the mail server. (couldn't figure out from the list of answers if you've already tried this);

Without outlook running, set up a brand new outlook profile using mail in the control panel. Call the profile anything you like. Use the switch to force outlook to ask you for a profile. Start outlook, use the new profile, try the mail server;

Try making a brand new user in XP in admin group, new mail profile with old username and password for exchange server, try the mail server.

This'll sound wacked, but take out client for Microsoft Networks, File and Printer sharing, Internet Protocol - boot and put back Internet Protocol complete with all those lovely settings you probably have memorized by now or will write down before removing tcp/ip. TURN OFF register this connections settings in DNS (DNS tab of advanced). TURN ON disable netbios over tcp/ip, boot and try the mail server. The first part get rid of any nasty leftovers from you've already tried all the settings every which way. The second part will prevent your computer from talking to the exchange computer in a certain way.

Just a comment from the writer of #28.

Think you are having wierd user authentication SID problem. Your username on the domain that the exchange server computer belongs to has a sid. your username on your local computer has a sid. they are notthe same. Your computer and the exchange computer would like to believe that they should be the same. They would so like to believe it that they are presenting your local sid to the exchange computer as being one of its sids, but of course its not- its your sid. You sid isn't allow access to the mailbox. It's sid is. When you access your mailbox from someone elses computer, it doesn't suffer from sid confusion. This maybe because XP is a little odd about networking.

Here's something else I just noticed.

Whenever I put "umr.edu" at the end of the server name I immediately get the error "The name could not be resolved..."

If I take out that part (umr-mail5 or minermail) I get the username/password prompt and the get the "The logon credentials supplied were incorrect..."

When I put the IPs directly as the server name I get the password prompt.

Make sure the login name of your computer is the same as the profile for exchange (jsmith -> jsmith). So does the password.

Hi

My friend I would like to help you in your problem and need more info.Please answer these qustion and send me an email or post comment in your Q.
1. Is Outlook version in your dorm pc the same as the one in the campus which does work?. install the same version of OS and
outlook too.
2- Could you try and check your dorm PC in the same network connection as the one in the campus?
3- Could you try and check another PC in the same network connection as the one your dorm?
4. what it the connection type in the dorm pc is it dial up or direct network connection.?
5- Did The tech support checked the setting in your dorm pc if not take it to them.
6- i would back up my dorm pc then make an image of a campus then restore into my pc and check.

Good luck

I'm on spring break for the week so I won't be able to try out any of the suggested answers until April. Thanks for all your help so far and please keep the suggestions coming!

Given the volumes of info in this thread thus far, it's safe to assume that this isn't necessarily a problem on your end.
Exchange 2000 is active directory aware, if there is any problem with your regular user account (permission wise) then it maysomehow be affecting your exchange account, especially since the problems started when they upgraded.
Have the helpdesk staff check not only the settings you have as a user(in AD AND Exchange), but also the settings for your computer. Your IP address may change everytime because of their DHCP server, but your network card's MAC address doesn't.
This shouldn't be a problem if all students are using "guest" access, but it may be a problem if each computer has an entry in Active Directory (usually identified by NetBIOS name) that was corrupted during the Exchange2000 install. This would explain why other net services are available to you AND you can use other student's computers to check your mail.
Another major problem is if the firewall you were using was ZoneAlarm or ZoneAlarmPro, they mess up alot of settings, from becoming scattered all over the registry to corrupting the TCP/IP stack.
you may need to skip the helpdesk and go right to the sys. admin., because they would have therequired permissions to set everything straight.

Open a command prompt and try the following:

ipconfig /registerdns
nbtstat -AA

This will refresh the DHCP, WINS and DNS entries.

When using your computer or a lab computer to access the network resources, do you have to login to a specific domain on the campus network?
For example, before entering Windows, do you have to supply a username, password, and domain? If so, are you able to successfully login to the domain on your PC?

Also, does your university offer any network shares for you to access for personal storage? Are you able to access these resources?

Are you able to access any network related resources atall, or is Microsoft Outlook the only thing you are having trouble accessing?

It is obvious you have a DNS resolution problem on your PC. Talk with tech support and have them work on your DNS issue with you on the phone..

I have been reading all the comments you have had up to now and noticed that you are running winxp. I had the exact problem with road runner connection to the school I work for and we tried everything and would not let me connect to the exchange server. I also got the same login box and message you got. I for the sake of everything else as you reloaded windows with win2000 pro and everything with the same settings etc works perfect. I do not however get to browse the network with network places master browser but we're working on this, all I see in the master browser window is my domain and my system. Although I can find all domains and etc in the directory, but not through entire network connection as stated. We also tried everything and at work my system works fine in every way and I have windowxp pro installed. It has been a very fustrating problem that should not happen but until I reloaded with windows 2000 I could not get mail except through as you at the school or through the IE connection. Hope this helps and I know probably not the answer you are looking for, but it was the only thing that has worked for me. I also have other employees I support who have the exact problems with browsing the network and all are setup the same with dns, wins etc and outlook works just fine.

Well, I'm back from spring break but now the problem is worse. I can't log on to anything that requires my user id and password let alone check my email. I'll respond to all of the answers as soon as tech support can fix my account, or maybe when they fix this it'll fix my email problem too. I hope!

It may be that the outlook you installed may be corrupted. I would suggest to backup all your mail by exporting file *.pst and include all your email and calendar and everything then uninstall outlook completely. Restart the machine and install it again. It most likely got messed up when you installed it or when you modified something. Did you mess with the Registry at all? anyways, try to uninstall it and resinstall it and dont forget to export the file. to import all your email use the importunder the file menu.
good luck.

OK, there were some problems with my password for some reason and I had to reset it again. I can now use my username and password for everything...except email through MS Outlook. I'll be trying out the answers as usual now.

Did you upgrade from a previous OS or do a fresh install? Either way, in the face of adversity, is it not best to backup all your data and blow the f@$%ing thing away! Reinstall XP from scratch and install the minimum (just Office and nothing else).If that doesn't work there may be an incomatibility problem between XP and the Exchange server config. You haven't mentioned anyone else on campus running XP so maybe thats the problem. If the rebuild is unsuccesful, try a fresh 2K install with onlyOffice on it and try again. If that works, then try upgrading from 2K to XP and see what happens. It sounds a bit of a chore and it may not find the problem but at least it will get you working!

If you ever want to work on this problem again, make a Ghost image of your HD and chuck it back on at a later date..... have fun!

A few things to try;

Telnet to the servers ip address on port 110
ex: telnet 192.192.192.192 110
when connected type user (username)
then Pass (password)
if you unable to login in this manner than the ISP (your school) has your alias name different from the NT Login name on their server and must make them the same.
If you are able to login in the telnet manner above then you have an outlook issue but by using telnet above you can remove half of the troubleshooting from the equation.
You mentioned that putting the IP address of the server prompted you for the user name and password which means this should work.
Good Luck Chembrother

Like my advisor in college said, "You have a problem." I have read from start to finish. You have had many good suggestions. After you have tried answer 32, I would suggest that before you reload OS, just try a new NIC. It might not fix the problem,but I have had problems like this that were fixed by replacing the NIC. It will only take a few minutes to try. You have pretty well covered the software options.

Good Luck!

You said you did a fresh install of XP long before the problem started, but since then things may have changed. I picked up on the fact that you enabled and then disabled XPs own firewall. I know it shouldn't make a difference, but it might, so maybe it's worth reinstalling again to give you a virgin install to work on. There may have been apps/add-ons that have been installed that are conflicting with the OS.

Thanks for the feedback.

In a nutshell, the problem is this: You CAN NOT access your email account from YOUR computer using Outlook.

Let’s break down your problem as follows:

Point 1:
The University uses Exchange for their mail server. You can indeed access your email account through other campus computers using Outlook (configured for your account). Furthermore, you CAN access your email using the Web interface from your own computer. Therefore you can safely assume that the University’s Exchangeserver is not the problem.

Point Two:
However, you used to be able to use Outlook to retrieve your email from your computer. Therefore, you can further assume that the problem was created by something done to your computer’s mail and/or profile settings.

Point Three:
All hardware is functioning properly, as you’ve verified.

Solution:
Therefore, the solution MUST be addressed in your configuration. If you correctly configure your software, you’ll solve your problem. (“Correctly” is the key word here.)

All of the “correct” configuration issues are addressed in the aforementioned answers. Therefore, you have to review all of the settings – again. It’s obvious that you missed something that was already suggested. If you did indeed look at – and verify – everything that was mentioned, the thing would work. Go over it – again. And, with all due respect, make sure you heed this advice: Don’t overlook anything. Don’t assume anything. Verify everything. (I suspect that your problem lies within the settings for the Configuration of Exchange settings for user profiles.)

If you feel so inclined, you may want to reload Windows XP. It may notbe necessary, but after so much “tweaking” attempting to solve this issue, some things may have become corrupted.

(continued...)

Has anyone else successfully logged on to the Exchange server from your dorm computer?
