SYMPTOMS
When you deploy an image on your network computers, the computer names that are generated by Sysprep.exe may be duplicates. After this occurs, you may receive an error message that indicates that the computer names that were generated by Sysprep.exe already exist on your network.



CAUSE
This problem can occur after you used the Sysprep.exe tool to prepare a sample computer for cloning, and you used the &quot;ComputerName=Auto&quot; entry in the Sysprep.inf file to generate the random computer names. This problem can occur because the Windows NT 4.0 Sysprep.exe file version 1.1 does not use the proper logic to generate random computer names.
