how to remove first Exchange Server 2003 computer from the administrative group when the Server no longer exists

Posted on 2011-04-19

The environment is:

Exchange Server 2003 Standard (SP2?)

Initially, Exchange was installed on a single server
A new server has been added to the Exchange organization as the old server was starting to give problems and all mailboxes except one, were moved to the new server
Before I could move the last mailbox or transfer/replicate any of the roles & public folders as per the Server crashed and died, and can no longer be revived.
When I access Expand Public Folders, and then try to expand Offline Address Book, (as per kb 822931) I get the following error message

"The operation failed due to an invalid format in the http request. Verify that the host header is correct for the virtual server
ID no: c1030af0
Exchange System Manager"

1. How do I change the new Exchange Server to assume all of the Master Exchange Server roles with the old one being dead?
2. How do I get the last mailbox reconnected to the new Exchange Server (I have a full .pst backup of the mailbox)
    ( I tried to delete the mailbox from AD User Active Directory Users and Computers Console & Created New Mailbox on the New Server, but I cannot get outlook to verify the user when setting up his profile on outlook)

Urgent assitance will be very much appreciated

Kind regards

    Go the exchange system manager and delete the old exchange server.
    Install ADSIEDIT and and search for the old server and delete all references.

    Thank you, I deleted the Old Exchange Server from the Exchange System Manager
    It seems to resolve the user's full name in the mailbox setup screen, and I do not get the error while expanding public folders anymore
    I have not been able to find a search function in ADSI Edit though, so I am not sure if there are any other instances or references of the old server left in the AD
    Will that be problematic? Is there a specific way to search, or an alternative way to search for references of the old Server?
    Most Appreciated
