We migrated an Exchange 2003 to exchange 2010 running on a new Windows Server 2008 R2. The old Windows Server 2003 with Exchange 2003 does not (physically :-)) exist anymore.

On my Exchange Server I saw event id 5006 MSEchangeTransport. When running the Get-ExchangeServer cmdlet I still saw the old exchange server which doesn't exist anymore.

I've followed these steps (http://support.microsoft.com/kb/833396) to go to CN=Configuration, DC=Domain_Name,DC=com, CN=Services .... CN=Servers

Now I see on the CN=First Administrative Group > CN=Servers the old server as only server listed and on the CN=Exchange Administrative Group > CN=Servers I see the existing server as the only server listed.

Can I just remove that old server from the CN=Frist Administrative Group > CN=Servers or should the new server also exist in the First Administrative Group instead of only in the Exchange Administrative Group?

I'm using ADSI Edit on the Domain Controller, I suppose that there is no difference on using it here or on the Exchange Server itself?


Just delete the old server. The new server should not exist in both places, just its current location.

It doesn't matter where you run adsiedit from.

  • thanks. I had to use some extra cmdlets on the exchange server like "Update-Recipient" because something was pointing to a deleted object in AD. – juFo Sep 27 '13 at 14:26
