Bypass user GPO in Windows Xp / 2003

During some security testing in a high security enviorment - I discovered that by using the "run as" or "the runas /noprofile" I could bypass user GPO settings completely.

I e-mailed the security mail at Microsoft about it - and they confirmed that they had reproducedc the behavior - but said that the user restrictons where not ment as security settings - but just to stop the user from messing up their enviorment !?!?!?!

To reproduce it:

Set up a domain with strict security settings. Eg. Software restritions policies, hide local drives, remove "run", disable cmd.exe and so on.

Log on to an XP computer in that domain - make a link to cmd.exe - select "run as" on that link.

Logon with another user in the same domain - with the same restrictions - you'll see that the GPO's will not be loaded for that user.

Maybe not a big deal - but I thought you should know......
