Re: Finding a Hacker

Is there a way to restrict remote desktop from allowing access except from
my home ip address?

Where is "logging for logon success and failure" located? I assume it's a
GPO?
Can you give me some good keywords to search or linnks for info about using
these logs?

Thanks for your input.

Scott,
If that PC has been hacked, you will need to rebuild the whole domain. Its
really a question of whether someone is pulling your leg or you have been
truly hacked.
1) If you have set logging for logon success and failure then the the
logon will be in the security log.
2) You can't
3) No. I guess if someone had domain admin rights they may be able to
create an account you couldn't see, but if you thought they may have
domain admin rights you would have to rebuild anyway. Is there a local
account on the PC?
4) No.
Your problem is not restricting remote desktop connections. It is what
people are able to do on your domain. Your best case is that users are
local admins of their machines and someone has done this for fun. Your
worst case is that a hacker has found the remote desktop opening and
cracked a password.

One of my clients has a Win 2003 standard PDC with about 10 winXP
clients. I've had AD setup and been running fine for years. Last week, I
was sitting at one of the XP clients on the domain and suddenly I got
logged off and a user "userHacker" logged back in. I had to hit
ctrl-alt-delete and logged myself back in.

After about 60 seconds, it happened again. So I cut off access to the net
and looked at the pc's user profiles and noticed their was a local
account for "userHacker". I deleted the profile and left the pc off line.

I should mention that I have Remote Desktop and pcAnywhere ports open in
the firewall for this XP machine.

1. Is there a log within the PDC AD that would show a record of users
that logged into the WinXP machine?
2. How can I determine which port the hacker is coming through?
3. Although I searched AD's Users and Computers applet, I couldn't find a
"userHacker" account. I'm assuming the account was a local account on the
XP machine. Is there anyway for him to have created an "hidden" account?
4. Does "Remote Desktop" keep any type of activity log that would help
me?

Any ideas on restricting remote desktop connections by user account or ip
address would be appreciated.
