Hello, Yesterday i added a new windows 2008 server in our Windows 2003 domain. We also have 2 exhcange 2003 servers in the 2003 domain. The Active Directory upgrade went without problems. But when i now want to delete a user or disable a user on my W2003 server i get an error: "Microsoft Active Directory - Exhcange Extension has encountered a problem and needs to close. We are sorry for the inconvenience." in the event logs i get: Event Type:ErrorEvent Source:Microsoft Exchange ServerEvent Category:NoneEvent ID:1000Date:29/09/2008Time:9:31:59User:N/AComputer:SRVR1Description:The description for Event ID ( 1000 ) in Source ( Microsoft Exchange Server ) cannot be found.
