WinXP & Win2k Group Policy

Ok this is kinda complicated ... may be just for me.

I need to write a group policy or registry hack for win200 & winXP to have log domain users as Power Users.

I would do it using PDC but I'm using Samba for that and I didn't quite figure out how to do it yet not sure if its possible. I know I can execute logon.bat script ...
with line like this
REM Update (silently) the client's registry
REM Depending on what you import, you need the appropriate user rights
REGEDIT /S "\\server-name\NETLOGON\winxp.reg"

That should take care of the mergin (loading) registry

I've tried to do add Domain\Domain Users to Power User group and it works fine on win2k but doesn't work at all for XPpro.



any help on how and what to use to accomplish this is appriciated .... hopefully I didn't confuse you all
