QUESTION POSED ON: 08 August 2008
I am running Exchange Server 2003 on Windows Small Business Server (SBS) 2003 with Windows XP Service Pack 2 (SP2) on all workstations. Recently, we've been having connection issues. A few Microsoft Outlook clients cannot establish connections to the Exchange 2003 server; however, this only occurs when other clients are successfully connected to Exchange. When I disconnect some of the existing sessions, the clients that were not connecting seem to connect successfully. Errors are also received when trying to connect to Outlook Web Access (OWA) while other sessions are active. Similarly, when some of the active sessions are disconnected, OWA works perfectly.
It appears that a maximum connection limit is set up for the Exchange server, yet the connection limits set up for the protocols far exceed the number of active workstations. Our network is small, with about 20 to 30 workstations. Can you please advise me on protocol connection limits and how they work? Or could it be another problem that is causing this to happen?
