Local admin privileges gone haywire

F

Frisk

Hi, i hope somebody can help me.

I run a pretty largish network with 2 domain controllers. We've just
relocated our company to a large building so i've had this opportunity
to implement a solid network environment.

Until yesterday morning i had everything running great.

I split the netowork using organisational units and group policies.

e.g.

tech
sales
management

etc

all worked fine, the sales group all have very restricted privileges on
their workstations, tech could join domains and do general network
admin etc.

i thought that the icing on the cake would be to allow anyone in the
tech group to automatically logon with local administrator privileges
on any machine (theres around 200 workstations here) using their logon
(i know i should've just kept with using the local admin logon). So to
do this i added administrators to the restricted groups in the tech
group policy and made office tech (the security group which all techs
are members of) a member.

After forcing a gp update this seemed to work, all techs automatically
have local admin privileges on any workstation they logged onto, but
after a little analysis, i decided this was a little unsafe and removed
the restrictive group.

I did a few other little edits of other gp's (ive been tweaking the
network) but nothing major and nothing that should have any effect on
anything but now heres the problem.

When i log on as the domain administrator on any workstation, i no
longer have local administrative rights on that machine, unless i
rejoin the workstation to the domain, and i dont really want to have to
do that with 200+ machines when i've done it already.

Also, the tech group still always have local admin privileges on
workstations (even workstations they've never logged onto before) even
though non are members of any administrator group and i removed the
restrictive groups policy.

Just to make sure, ive just now created a fresh new tech user called
roger.rabbit

Here's the gpresult output

When you implement restricted groups it erases the existing contents of the
group. When you remove the policy (in Windows 2000) the settings are not
backed out. You simply stop enforcing the membership. I believe that some
of this behaviour changes in 2003 - but haven't tested it yet. Apparently
you are able to back out these changes in 2003.

Anyway, to fix this you need to repopulate those groups. The quickest and
easiest way is via restricted groups again. Another option is a startup
script. Another option is to use CUSRMGR with a script or in batch.

The first two options are discussed here:
