Help!-Server Crash


   Our Exchange 2000 server died.  I'm trying to install it on another box, using the same server name,
to avoid having to update 1000 user PCs.  I've removed every mention that I could find, of Exchange
in AD. While doing an install on the new server I get;
'The component 'Microsoft Exchange Messaging & Collaboration Services" cannot be assigned the action
"Install” because:
-A server object for this server "server name" already exists in the Administrative Group "First Administrative
Group".  You must either remove this server object before installing, or run setup with the "DisasterRecovery"
switch if you're attempting to recover this server.
Any ideas on what I need to do?  Thanks in advance

I don't think you ever want to install any computer with the same name as another.

If I understand your dilema correctly, I think what you should do is install Exchange on another server with a different name and then move the mailboxes of the 1000 PC users to that server using the Active Directory USers and computers snap in.  By using this Move utility within the above mentioned snap in, it will change the name of the home exchange server for you without having to go to each individual pc.

What you should have done originally was to install the server using the same Computer name and run Exchange 2000 setup.exe from the Exchange 2000 disc with the /disasterrecovery switch.  This would have used the values present in Active Directory to install the Exchange server.  If AD is still complaining about existing data you might still be able to do it.  If you have a good backup of AD you might consider doing an Authoritative restore to recover the Exchange data you deleted from AD.  It still won't help you recover any mailboxes that were lost.

If this fails, check ADSIEdit from the Windows 2000 Support Tools and look for Microsoft Exchange System Objects container in the AD tree.

This is a delicate operation and not very well suited for remote management through a bulletin board such as this.
