problems deploying XP SP 2 with GPO

Hi,

Has anyone encountered the same problem ...and has a solution ? I'm trying to deploy XP Service Pack 2 on a network via group policy (server is Win 2K). Have double-checked the whole procedure, and nothing seems wrong but the SP 2 is NOT installed. When using GPRESULT or RSoP on the client machines, the policy IS listed however. The server is Win2K in the French language and the clients are Win XP in English (SP 2 in the English version as well). Could there be a problem due to the mix of languages ? I've followed the same procedure on another network where everything is in French and the deployement worked perfectly.
