We have about 60 Windows XP machines, some of which just don't seem to receive Group Policies. We can tell quite easily because we have some login scripts that are distributed to machines on the nextwork. What is strange is that the P: drive which is mapped by the Home Folder in AD rather than through a login script is always mapped which means that, at some point, the client PC is connecting to the DC.
I have checked the following :
There are folders with GUIDs in the sysvol folder on our AD Server.
If I run the login scripts manually, they work.
