Computers randomly joining domain
Posted on 2007-08-06
I have a windows 2003 domain and somehow over the weekend a computer joined my domain called NICK-DOG. None of the computers in my organization are named like that, atleast not by me. When I remote desktop into the computer, it connectes me to a computer with the proper naming convention that I have set up for our organization. The computer that it directs me to has a valid computer account in AD. This happened last week with a different computer name and I simply deleted it from the domain. My questions are...
how did this computer join my domain without my authority?
How do I tell who joined it to the domain?
How did it join under the name NICK-DOG when it is named something else?
How can I prevent this from happening again?
