Outlook 2007 Setup cannot connect to server. Name cannot be resolved...

Ok massive frustration here.
  I've setup several machines with Outlook 2007 SP2 at this location. So far no problems...expect with this ONE MACHINE.

  You know the error: "The name cannot be resolved. The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action"

 Now I KNOW  the server is setup properly because we have many external connections going on. I have several computers from this remote location also setup and working just fine.
 This machine is running Windows XP Media Center Edition SP3.  When I try to connect I get the error above.

 I'm setting up through the "Mail" control panel item, NOT outlook itself.
 I've tried creating a new USER profile in XP, logging in with that and still the same problem.

 I can PING the exchange server from the command line as well.

 Any ideas?

Try logging in with a different user on that workstation and create an outlook profile.   I have seen profile issues cause this issue.   If you find it works with a different user then rebuild the profile of the user you are having issues with....

Check that the DNS server matches the others that work. It is possible this one PC does not have correct info to connect.

ok well the computers are both DHCP, so they are both getting assigned the same DNS information.

 Also, I tried creating a new profile, logged in with that user and tried outlook again with the same problem. So I don't think it's the profile.

Is there a HOST file on the PC?

how you are connecting to your exchange, RPC over HTTPS?  Can you check the connection connection status? are all the connections are successful?

Postmaster: what's a "HOST" file?  Not sure, but I can check.

Khurramullah:  Connection is PRC over HTTPS.  The computer 2 feet away is connecting no problem and with all the same settings.
