Default Can this be stopped

So i figured this out.

If i login as a test student (who is locked down VIA Group Policy):

As soon as it accepts the username and password, i unplugg the network cord. It logs in. I then plug the network cord back in. I am now at MUCH higher elevated privledges then i should be. This defeats ALL GPOs except computer GPOS. How can this be prevented, if possible?

Server 2003 SP2

CPU: Intel 3.2GHz OC'd to 3.4GHz
RAM: 1GB PC3200
Harddrive: .710TB combined Local and Network storage
Video Card: Geforce 6800 GT 256MB RAM
Motherboard: ASU P4P800
Sound: Onboard sound baby
Monitor: Faithful 21 inches of PURE CRT
Number of Programs Installed: 39 and growing: not counting games, (and yes i use them all)

Default Re: Can this be stopped

Well this would only happen the first time for a very short period.


Basically as the user logs in for the first time they will be using the domain default profile stored in \\{domain}\netlogon (if it isn't there it doesn't exist)

This default profile can have any settings you like and can even use local user policy.

Another solutio would be to use roaming profiles.

GP will also refresh as often as you tell it to as well or can be forced by using gpupdate (there are also tools that will do it remotely as well.

Using this is the only possible solution here. However there is no profile there. So how do i create one and then make it so that is where defualt profiles are pulled from instead of from the local PC?

Easiest way, or what I have been doing is logging on as a local user, changing all the settings I want to change .. wallpaper, registry tweaks, vbs tweaks, file/folder layouts - anything I could think of.

Logging off, logging on as local admin, going to my computer > properties then copying the folder to C:\Documents and Settings\Default User

This will make it the default user on the PC obviously

If you then copy that entire folder into the NETLOGON folder then thats it!

Also note that any registry changes you make to \HKU\.DEFAULT are not infact being applied to the default user, this is actually the account used by system services etc. or if no one is logged on (ie you can use it specify the wallpaper for the logon screen)

You dont actually get evevated priviledges. You will only get the default which should be "User" level but yes your right you can do ALOT more then you should.
I am working on a solution for our network right now but I currently dont have to time to implement my ideas.

It isnt priority for me either, but this client of ours is a school system, so once a student figures this out, this spells trouble. They can do alot of damage in a few mins of this elevated privledge level.
