MS Office (Outlook) 2000 Windows XP Pro, SP1 Used to be fine, but now it says due to a network problem it can't resolve the user name on the MS Exhange server. I can ping the Exchange Server using its unqualified name in a DOS window. I used the IP address that it returned, and pasted it into the Exchange setup in Outlook. It resolved the name immediately, and changed the IP address back to the unqualified name. Then it couldn't resolve again. I've tried uninstalling and reinstalling Office. I've deleted the profile, and started completly over. The user name and password are fine, because I can get any other machine in the office to work just fine with the same setup. I even went and bought and installed Office XP to no avail. All other network services are fully available. Any ideas? Thanks, Dodge

This is a long shot... Go to your "hosts" file in your computer and put in the exchange server name and the ip address... See if that helps... If you don't know how to do this. email me... Steve

Nope! Good idea, but it didn't work. Is there a way to completely eliminate Outlook from the machine. When I uninstall and reinstall, it still has many of the old settings, so at least that part of it is not being removed. Thanks, Dodge

Well, now you got me thinking... It is only this one computer that you cannot connect to the Exchange server with, correct? Is it Exchange 2000 or 5.5??? Little more info might help... Is anything else not working correctly??? Any problems getting to shares or the Inet??? Steve

Yes, only this computer. I can set up his exact account on any other machine (including another laptop in his same office using the same port). Shares and Internet work very reliably. I am a remote (California) user of the Exchange Server (Minnesota). Is there a way I can tell the version from my end? I can't help thinking it's a corrupt file somewhere. It was working just fine, and then it stopped. It was coincident with me adding another Internet Acct. (POP3 not Exchange) to his setup (within 1 day), so that could have something to do with it. That was his second Internet e-mail account set up under the same profile (it works fine). Microsoft mail worked fine when 2000 was still installed. I appreciate your continued thoughts. Dodge

I think you need to check with your Exchange Admin in Minnesota... It's possible they put a limit on the number of POP accounts...

I ran into this problem awhile ago, actually a tech I work with did. He ended up having to uninstall the TCP/IP stack and reinstalling the TCP/IP stack. Once it did this, the outlook worked. There's a Microsoft article on it, unfortunately I don't have the ID#. Hope this helps. Thanks, R
