Hi,
I do apply the group polices by creating the test ou and test user. But, the strange thing which i come to that when i logged in with the test user (gpo applied) on Vista machines the group policies get applied and works fine but when i logged on to the Windows Xp Sp2 machines any of the group polies doesnt work.

I dont no why it is happening may be becouse of architectural difference between windows Xp and Windows vista; 2008 server.

OR

Do I have yo install any patches on server side or client side?
