Group policy does not apply correctly on Win XP PC on a 2008R2 Domain

Hi,

I have a user that when logs in a specific PC from another child domain the policy does not apply correctly.

When tried the user to login to anothe XP PC from the same domain the policy works fine. Both PCs are on the same OU. On Event we get Event id:1202, SourceSceCli, Security policies were propagated with warning, 0x4b8.

On DC the policy results show correctly, more precisely we want to remove run from start menu.

Tried to delete registry entries, removed the PC from the domain, deleted the user settings, but still same error.

Thanks in advance
