Crash while upgrading from 7.5 to .0 If a user is explicitly added as a trustee, and that user is no longer in Active Directory, the server manager wizard crashes on updating/adding trustees. It fails because when it performs get-aduser using the SID the return is nul and it causes the wizard to crash.
