All other systems that the Sys admin put in that particular OU takes effect, except this particular system. Verified on the client system that it is in correct OU, by running gpresult.exe. Already had admin do a gpupdate.exe on there end. I rebooted system and re-authenticated back to the domain, but still to no avail. Anything I can try from the client side of things, or maybe even the server side? Already gave it a couple of days to replicate across domain, but still to no avail. The client OS is Windows XP Pro.
