XADM: Exchange 2000 Setup Doesn't Finish with Error Message: The User Name Could Not Be Found

During Microsoft Exchange 2000 Server setup, you may receive the following error message if the user account that you used to start Exchange 2000 Setup is not a member of the domain that Exchange 2000 is being installed in:

Currently, when you install Exchange 2000 in a Microsoft Windows 2000 domain, Setup creates a group called "Exchange Admins." This is a Windows 2000 global group, which can only contain members from the domain that the group was created in. Setup creates this global group and then tries to add the current user account (the account used to start Exchange 2000 Setup) to this group. Before it adds this account to the Exchange Admins group, it does a lookup in the local domain (in which the current user account is not found because it's in a domain other then the installation domain), and thus fails with an error from not finding this account.

Log on to the server as "Administrator." Or, if you don't have access to log on as that account, create an account with the same user name that you are logged on as in the domain you are installing Exchange 2000 in.
