Group policy tatooing with restricted group ? or strange behaviour !

Hello,

we have Windows 2000/Xp clients in our Active Directory.

Configuration 1 --> We had a GPO applied on computers that defined a
restricted group for BUILTIN\Administrators. (So, if a user wanted to
add himself to his local administrators group,his user account was
automatically removed from this group).

Configuration 2 --> During three months, we have changed this GPO and
the restricted group was defined witht the "member of" parameter so a
user was able to add himself to the local admin group.

Configuration 3 (= configuration 1) --> Then, as some of the users knew
the local admin password and have added without autorization to the
local admin group, we have configured the restricted group as before
(and so users are removed from the local admin group).

now the problem ...

If a user power on his computer with the network disabled or if the GPO
is not applied for any reason), the local admin group is identical to
what is was during the "configuration 2" and so some users are local
admin ...

Is it normal ?

Thank you

Hello Eric,

If the policy change is not applied because the machine was not on the domain
when you made the change, this is normal. To apply the new policy the machine
has to be connected toi the domain.

Thank you for your answer but perhaps I was not clear enough.

There is no policy change when the problem occured. The user is
retrieving an OLD group policy when it is not connected to the LAN.

If the user added his account during Configuration 2; then, even if the
configuration 3 deleted the user account that was in the admin group;
if the user unplugged the network and reboot, his old user account (in
configuration 2) is present in the local admin group.

I hope I am clear enough this time :)

thanks

Hello Eric,

Run after the 3rd change when the user is logged in rsop and check  if the
policy is apllied with the correct setting.

First off as a general practice, you should be changing the admin password
on a regular basis.  If someone has compromised the password then it should
be changed immediately.

As Meinolf already indicated you have to be connected to the domain for the
restriction policy to take effect.

I agree but my question is "how can I define the "default" users that
have to be member of the local admin group when the computer is not
connected on the network and so the group policy is not applied?

Thank you
