Assigning the same local administrator name and password to every workstation in a Windows domain creates a security hole. If someone decrypts this common password they gain administrator access to all other machines with that same password.
Systems administrators should change the built-in administrator password on all of their systems at least every 30 days. The local administrator passwords should also be changed immediately when there is turnover in the IT staff.
Lieberman Software’s Random Password Generator can randomize local administrator passwords on even the largest domain in just a few minutes. When randomization has been completed, cracking the local password on any single machine does not provide any clue as to what credentials will work on other machines.
