Is there a way to see if someone added a user account to our active
directory that dows not show in ADUC?
 
What do you mean doesn't show up in ADUC? If it is a user object within the
name space of AD domain it should show up (Unless of course someone modified
permissions on the object).

That's what I am trying to find out. How can I check the permissions if the
object doesn't show. Saw a strange user named "sistem" and I immediently
deactivated that account, and changed the server password. I am looking to
see if any other unusual activity. Anything I should look for?
 
I would find it very unlikely that there is something that hidden if you are
logged on as the domain admin.

Just use the "Saved Queries" and create a query to return all users.

Do you have an FTP site that may have been compromised? If you found a user
account such as 'sistem,' I would be leary as to think what else may have
been added or compromised, such as an auto-instance of ServU or WarFTP
server installed along with it?

That is exactly what happened. Don't see anything yet, but keeping a close
eye on it. Any suggestions?

Scan it using a scan tool checking each and every port to see which is
listening. You can also run TCPView to find what ports are open and what
executable is listening. This should tell you what port the FTP server, that
is if it is FTP, is running on. Once you find out, FTP into it on that port
and see what data shows up and search your drive for it. If it's a folder
that you can't delete or find, there are methods to delete them.

Let me know what you find out.

Looks like everything is ok for now. I have been running Process Explorer
and TCPView and do not see anything our of the ordinary. In addition, I have
a logon script that tracks logons on our network and places them in a access
database on a remote machine. Again, nothing is showing up that is
suspicious.

Thanks for your help.

Good to hear. At least you now know what to look for. Keep in mind if FTP
access and it's an anonymous connection, it may no show up looking at
logons.
