How to Identify1- Go to 'Configuration' tab > 'Computers'
2- Right click on 'Add computers'
3- Type computer host name '22222' and click 'Add'. The error is displayed.

Workaround / Fix DetailsAs http://support.microsoft.com/kb/909264 states: "In Windows 2000 and in later versions of Windows, computers that are members of an Active Directory domain cannot have names that are composed completely of numbers. This restriction is because of DNS restrictions."
Required ActionsIf you find a customer being able to add computers only with numeric host name, please collect the domain version and escalate to PSG.
