Outlook error message

[alp12]

We set up Server 2000 on the network last night and loaded on Exchange Server 2000 for shared calendering. It worked fine lastnight . When users logged onto the Server this morning they receieved an error message from
Outlook: "Outlook is requesting information from Microsoft Exchange Server. You must cancel the request or minimize Windows taskbar unitl Outlook closes message automatically."

Any suggestions on how to change and correct this problem.
We are running Server 2000 and Exchange Server 2000.

For sure I will guest DNS problem. Be sure you server is setup properly into your DNS... And if you can restart the dns service on your dns servers.
But this is only a guest.... I never experienced this problem...
