Client Installation Wizard Error 00004E25 Could not generate a unique name for this computer

When our service desk was trying to push image they were getting error message

“Client Installation Wizard Error 00004E25 Could not generate a unique name for this computer”

The server AXBMMGT02 could not generate a unique name for this computer

Contact your network administrator for further assistance Administrators should check the remote installation services settings to ensure the automatic computer name option is set correctly. This error may also indicate that the computer policy used to create a unique computer name has reached the maximum number of combinations.

1. We had rebooted the Ghost server.
2. Tried Domain Admin ID as suggested in following post
3. Finally I followed this port and it got resolved.

When I opened the OU I found tons of unique name like this .

Finally I deleted and ask the support engineer to start. That worked.
