Ravi, Try following and correct me if I am wrong: Goto AD Users & Computer, Users's properties, Account Tab, click on 'Log On To', click on 'The following computers'. Add any fake computer name. I hope this will solve the problem. Cheers, Sushil Bhalla > Hi, I have to create exchange users from Active Directory Users and > Computers.
