I have a Windows XP workstation that is running Outlook 2003 to connect to an Exchange 2003 mail server. The user reported that he was unable to receive any email. Upon investigating, I discovered Outlook was not connecting to the exchange server. I can ping the exchange server, and have DNS resolution from the troubled workstation. Since OWA is working perfectly for this user, and other users on the LAN are not having a problem with email connectivity, I simply attempted to delete the account form the workstation and re-add it. When I get to the "check name" step, Outlook stops responding. I have left it "not responding" overnight, and it is still like that in the morning. Running outlook in /safe mode yields the same result. I "think" I have been able to narrow it down to a RPC problem through some other methods, but don't count on it. Any insight would be GREATLY appreciated. Thanks!!
