Wolfenstein: Enemy Territory (ET) Problem

I am always kicked by PB (punkbuster) for the reason.
RESTRICTION: INADEQUATE O/S (S/O do not remember) PRIVILEGES
what is this and how do I fix it?
I already tried reinstalling the game etc…
Answer #1
1. SWEET u play ET! woo! i do too, greatest bestest free game evah!
2. Aaand your error:
"Inadequate O/S Privileges" (Punkbuster)
Punkbuster requires player's to be running their OS as a user with administrator equivalent rights, this is necessary for their cheater detection methods. It has caused some problems for people though, and Punkbusted have a detailed help page for this here.
However, also check for Adware on your computer: some adware has been known to change the user rights. Two very popular adware/spyware removal programs (both with good free versions) are AdAware and Spybot - however, this post on PlanetRTCW gives specific solution for VX2 adware, and notes "many programs do not repair [your user rights] when they remove [VX2, and maybe other adware]".

Hmm, turns out that second link from Punkbusted was more relevant than i thought.
It has a guide to help you go through this problem, with details on sorting out priveleges.
It is written for xp/2000, but i tried following the initial “Local Security Policy” bit and it all worked for Vista too.
try it, might solve your problem.
according to them, if it doesnt, you must have some form of malware or something.
Answer #5
Checking it out.
Answer #6
1) Then go to Control Panel => Administrative Tools => Local Security Policy. This will open up the Local Security setting window.
How do I find this ? Or how is it called in DUTCH …

Answer #7
