WMI query for checking computer name

Hi

I must be doing something wrong on this one, but anyway. I'm trying to use a WMI query condition for OSD TS "Apply Network Settings". If the computer name is like it should be added to a certain AD OU:

Select * from Win32_ComputerSystem where Name like "TST%"

It passes the Test query in the WMI Query Properties box when I'm adding the query, however it seem to fail during the deployment. I haven't checked the smsts logs yet, just wanted to know if I was doing something obvious wrong here....

Thanks.
