Exchange Server Email Issue

By infosystems ·
I had someone set up Exchange server on my Windows 2000 network. We only have dial up access for mail because we are out in the sticks! Any way, we have an ISP hosting our email services. We have a number of remote users that have our domain name email addresses, ie
someone@ourcompany.com. We cannot email them from the main office because the message is undeliverable and says that the email account does not exist at the organization this message was sent to. In other words the exchange server is looking for that someone@ourcompany.com email address here at our local server and can't find it so says it doesn't exist. Is there anyone that knows how I can fix this problem. I hope I have explained it okay.

Thanks

I am not familar with the term "out in sticks";
does that mean you a "in a galaxy far and away" from civilitation ?

solution 1: install outlook web access so they can check their email via IE.
In this case you have to create the accounts on your domain too of course.

solution 2: You need to relay somehow, or with a registered second domain or with hotmail. create a custom recepient in exchange that forwards to hotmail, hotmail forwards to the isp.
if you register a second domain, the isp has to create an second emailadress for the remote users with the 2nd domain. and you in the exchange you create a custom recepient with the 2nd domain email.


solution 3: did you check for a isp that can provide you with satelite connections. ?

I don't know if this applies: ?
how far away are the 2 buildings from each other, you could connect them via a laser or radio connection or fiber.

Here is something you need to check. From your question, your ISP us using the same domain name that your server is. Both are using "ourcompany.com". Therefore, when you are on your LAN, your server is 'authorative' for the domain. When you are outside on the internet (not on your LAN) then the internet DNS server is pointing to the ISP server where your email is located. As long as your Windows 2000 domain server is using DNS (2000 REquires DNS) it thinks it is authorative for that domain name and NOTHING will be sent out from your LAN which uses that domain name. Here are your options, as I understand..
1. Change your LAN domain to ourcompany.local. But since you cannot change a Windows 2000 domain name, it means a complete reload of your server and starting from scratch on your network. This is not recommended.
2. Set your email server as the ONLY email server for your domain. But this will mean that you will need to change the internet DNS servers to point to your email server, not the ISP. However, this raises a lot of more questions that we do not have time or space to discuss here.
3. Adjust your ISP domain name. Something like..... ourcompany2.com. This would need to be registered. Have the internet DNS servers point to ourcompany.com for your own server, and ourcompany2.com on the ISP server.

To put it mildly, your solution will not be simple. If you want to discuss details further, let me know, as I have had to work with this issue for a client.

Here is some additional information...
If your IPS is using ourcompany.com and the Win2k server on your LAN is using ourcompany.com, then ANY TIME you access any resource at 'ourcompany.com from the LAN; nothing, (I repeat, nothing) will get out to the internet. For example, if your ISP were hosting a Web site with your domain name, or an FTP site with your domain name, then no one on the LAN would be able to access that web or FTP resource at your ISP.

Since your internet connection is POTS (telephone) then for your own server to host your e-mail is definitely NOT the answer.

From my observations, you have only two options. And neither will be easy.
A. Change your LAN domain name to ourcompany.local. That will mean a complete reload of your server, your email server, your applications, etc. This would be a lot of work, but will solve this problem.
B. Get a second domain name, as mentioned above. Note: in this case, you cannot get a domain name like 'wan.ourcompany.com' because the root of this name is still 'ourcompany.com' and your current Win2k server believes it is 'authorative' for this name. It will never send any request for this name out, to the internet.
C. There is a third option, but it will cost you a lot of money. This would be to get a DSL internet connection and then have ALL email for your 'ourcompany.com' be hosted on your own server. Not on the ISP server.

You have some business decissions to make to correct this problem. How imporant to you is the solution to this problem? How much money are you willing to spend? How much time do you want to spend on this problem? The owner of this network will need to look at the entire picture, all the options, and make a decision.

As I stated above, if you have particular questions, let me know.

Best of Luck.
