We are an ASP who have a customer with 600 users who gets the message "Requesting data from Exchange server" several times pr. day. The Exchange servers and the Terminal servers are on the same 100 Mbit/s net with no firewall or routers in between. We are migrating the users from an Exchange 2000 server to a new Exchange 2003 server but the problem is the same on both. The TS are Windows 2000 and Outlook XP is used. There is minimal CPU and memory load on the Exchange serveres and other users have no problem when one of them hangs.
Do anyone have any ideas?
