Unknown built in account that was created by a trojan.


I have been battling with troy for a couple of weeks now, I'm starting to feel like a real Spartan! I noticed today when running the security baseline analyser that there is an account in the administrators group that I don't recognize. It is dale.chippen(suspicios no?) and the system will not allow me to disable or delete it because it is a member of the built in accounts.

What is going on with that?

Are you running Windows Pro or Server? Where do you see this account and in which container ?

Is this account listed as administrator account?
What is the full name of this account ? it is dale or dale.chippen?

If it is a member of built in account means GROUP and not user. If this is a user then it can be deleted easily using the Reg.exe.

Let me know.

I am running Windows 2000 Server for my Active Directory domain master.

The account is shown in a container called hyco/charlottetown which is an organizational unit in our domain.

The full name of the account is Dale Chippen and the user name is dale.chippen.

It seems to have been added as a member of the built in group administrators and I don't know how to remove it from this.

Well, I am feeling kind of stupid now. My other tech just arrived and tells me that he renamed the original administrator account to this a while back.

I will close the case and award you the points for your response.

Do you see this account in Builtin container?
Try to remove it from Administrators Groups in Buitlin container and then removing this?
