Re: Preventing Users from removing their PC from the Domain

Entering, or not, valid domain credentals at the domain prompt
during a disjoin in my experience only impacts whether the computer

I have seen the behavior where you don't need to enter valid credentials if
you are logged on as a local administrator. Whenever I have not been logged
on as a user that is not in the local administrators group either
explicitly or by group membership I can not even access the change name or
network ID settings as they are grayed out and a message shows that only a
local administrator can do such. I would double check that you are not
logged on as a user that is also a local administrator whether that be a
domain account or a local account. I would try it again but before hand it
would help if you could post in a reply the results for the whoami /groups
command for the logged on user that can remove the computer from the domain
and the command net localgroup administrators. Whoami can be downloaded
from Microsoft and I believe it is a RK tool. --- Steve

the PC is removed from the domain. Would appreciate more replies.

There is no magic bullet to prevent local administrators from removing
