I would like to why Group Policy don't correctly apply to all the
workstations in my company!

Here is the configuration :
- Workstation are all Win XP SP1 + Novell client 4.90 SP2 + ZfDAgent 6.5
(not SP1 yet)
- A User policy package created with Group Policy configured for XP
- A Workstation policy package created for Remote control (is it really
necessary?Can I include it in the user policy package?)

When login with a user account on a workstation, Group policy sometimes
apply, sometimes not!
I can't find any TID explaining how group polivy work (except TID10065126)

Can anyone help me for troubleshooting this issue?
