I was being following advise about fixing a problem and the instructions stated to do the following command from the command line. regsvr32 /u Now I am getting errors in the logs and the exchange server is not loading. Any help?

regsvr32 /u is normally followed by [path]\[filename]. The command unregisters the file. I never knew what the behavior of the command would be if you did not enter anything after the /u. Now I have a clue. Now, what you are going to need to do is to determine what files need to be registered again, and register them to get everything back into shape on your server. Probably the best way to do that is to go to the event logs and look up each warning or error event and look up the event id and source to determine if there may be a file mentiooned that needs to be registered. Were I one of the mystical Exchange gurus, I'd probably be able to tell you, but, alas, I am not. \\Steve//

I have sorted the log and this seems to be the error that is prevelant. Does this help? The MAPI call 'OpenMsgStore' failed with the following error: The Microsoft Exchange Server computer is not available.

What are the exact errors in the event logs?
