If other computers get this GPO fine I won't conclude that it's a corrupt gpo. Excuse me but I have some basic questions:
- what setting(s) you are looking for are not being applied? Are they in computer section or in user section?
- at what level the gpo is linked? are the computers all under that container?
- Did RSOP show what gpo(s) were applied? and what is the winning gpo for the desired setting(s)?
- Did you see any event logs saying that gpo has problem to apply?
