hello
we are running Win 2008 R2 domain controller with SP1. I have strange issue with one user account. the stange behavior happened, when I try to add this account to local administrators group on any domain member server. when I type the user name in the Select Users, Computers< Service Accounts, or Group" box and click "Check Names" button and got the windows for the Name not found. what I do, click the Locations button and select Entire Directory, then the AD can find the user account.
can anyone explain why this happen?
