Have you transferred the "localsid" from the old to the new server?

Sometimes that helps:

        change "domain logon" to "workgroup"; new start
        change "workgroup" to "domain logon"; new start

Sometimes you may need to change the computername too. But that leeds to  
problems with the profile ...
The background may be some information about the old server is stored  
somewhere in the client's registry.

Viele Gruesse!
