Here's my situation -
We are running Exchange 5.5 on a Windows NT 4.0 server
We have a Lantronics Remote Access dial-in box (LRS2)
Our dial-up setup has always worked fine...but now all of a sudden our XP clients are having problems. They can dial-in and login to the domain. But when they go to Outlook it's as if the Exchange server can not be found.
If I ping the ip address of the exchange server it pings fine. If I ping the name of the exchange server it doesn't ping. I've tried putting the IP address in for the server in the Outlook profile, but I still can't get email to work.
