My portable is setup for networking with TCP/IP protocol and running W2K. I can connect and browse web pages through my proxy server when I am connected to my network. I have setup a dial-up Network connection to the internet when I am away from the office. The problem is the following : I cannot browse to any web pages when I connect through my dialup connection. I receive a DNS error Server NOT Found. It looks like the connection is trying to locate the DNS server on my network. Why ? I can ping the IP address but I am unable but unable to bring up any web pages ! I have configured the DNS for my TCP/IP protocol that was given to me by my Internet provider in the Dial-up connection Server Tab. What I am missing ?

Thanks,

Ray

Try changing to automaticly detect settings. In Ie go to tools then the internt options , then select the connections tab, then choose lan settings. You might have to switch between the settings when you are on and off the lan. Worth a shot hope it helps.

Try this, dial-up to the internet then go to a command prompt and type "ipconfig /all". When that comes up find your dial-up adapter and see what ip address is listed for DNS server. Verify that it is the same ip addres that your ISP gave and thatit is not the DNS address of your local server.

Verified the IP address, it is the one that my ISP gave me !

Any other ideas....

Thanks for your input !

Just checking, but when you go in IE >tools >internet options >connections. You do have a dial-up connection in the dail-up settings area right?

Let's verify that it is or is not a problem with your machine and not a problem with your dial-up ISP. Add a new DNS to your dial-up configuration. Make it the same IP as the one you use with your office connection. Move it to the top of the list ordelete the other one. Open a command prompt and ping the IP then try pinging it by name. Resolved? Your ISP has a problem. Same problem? We need to investigate further . . .

Hi,

I performed the test like you mentioned ! I am able to ping website's by IP address and also able to ping by names. This test was successfull with my office DNS configuration and with my ISP configurations. Unfortunately I am still unable to bring up any websites with my Internet browser !

Thanks for your continued help !

What version of IE are you on? Maybe you should upgrade to 5.5 or if you have 5.5 uninstall it and reinstall it. I wouldn't recommend upgradeing to IE6 yet (its to new). Another test, dial-up and open a command promt.
Type "nslookup www.google.com". In the first part of the returned data is "server:" and "address:". the address should be your ISP's dns address. If it is the I really beleive that it is an IE problem. If it isn't your isp's address then your configed wrong somewhere.

I am presently using Internet explorer 5.0. The nslookup test returned the following : Can't find the Server name for address 127.0.0.1 Timed out. Default Server : Uknown
Address : 127.0.0.1.

This address is Microsoft IP for testing the TCP/IP. I was unable to find where this address was being picked up. I thought it might of being because it was in the hosts file, but when I deleted it from here it still did correct the problem ! I think I might try to reinstall internet explorer, but its a long shot.

Thanks again !

OK now we are getting somewhere. 127.0.0.1 is the loopback address. Your problem lies in that you are not getting proper DNS resolution. (positive of that now). Just to double check-- connect to the internet through the dial-up and go to the command prompt and type "ipconfig /all" check for the DNS entry for the PPP adapter. It should be the one that the ISP gave you. My other thought is that you shouldn't have to set any of the IP settings for your modem, try this, right click on my netwrok places, select properies, then right click on your dial-up connection (thats the default name) or what ever yopu named it, then select properties, go to the network tab, highlight tcpip and selct properites, both of the top radial buttons should be selected (the ones that say basicly get the info automaticly). Now click on the advanced button, the general tab should have both boxes checked, the dns tab sould have NO enries in the big white box (if there is remove them) append primary... and append parent... and register this... should be the only things set on this tab, on the wins tab ther should be no IP addresses in the big white box and enable lmhosts lookup should be checked. Say ok to everything on your way back out of that and try it again.

I just wanted to thank you for your help ! Sorry I couldn't give you the Tech points. You should be able to distribute the half points !

GOT IT!! It isn't DNS after all - it is the Proxy server!!

Got to IE Tools>Internet Connections>Lan Setting and clear all of te check boxes when you are connecting via the dialup. IE is still looking for the Proxy whn you try to connect via dialup!!

Hi,

You were half right! The problem was with MS Proxy client that was installed on the portable. Once I uninstalled the software, I was then able to surf the net. It looks like MS proxy expects you to connect through a proxy even though you specified it not to in the IE>tools>connections>LAN setting's. The only downside is that now we cannot retreive our internet email through the proxy server on our LAN since the client was uninstalled. We used it to be able to download the external internet email accounts for all clients! We have not configured MS Exchange for our external email accounts with MX records. I guess we will need to in the future.

Thanks for all your Help !

Did you read my very first answer? I think maybe you are abuseing this forum. The points in this forum are to keep the GIVE and TAKE system going. Since I noticed that you have never answered anyone's questions here and have only ever asked this one question I believe that you are a FREELOADER and just here for the one shot question. If that was your plan then fine, your problem is fixed. Now go away!
