Solution Because of this Remote Administration should be DISABLED. If this is not viable then the only way to prevent an unauthorized users (those with accounts) is to remove the "Access this computer from the Network" user right from the "Everybody" group and give this privilege to Administrators only.
You may want to verify that this is truly the case. Most of the time, the only thing that "Log on from the network" affects is services available via IPC$. That's why you see services that restrict users on the basis of logging on locally, logging on as services, and even logging on as a batch file. Given that this service doesn't seem to be impersonating users, I would be surprised if that right actually shuts down this avenue of attack. If you've already verified this, my apologies. It sounds to me like disabling it may be the only really safe choice. ----------------------------------------------------------- David LeBlanc Internet Security Systems, Inc. | Voice: (678)443-6138 300 Embassy Row. | Fax: (678)443-6479 6600 Peachtree-Dunwoody Road NE | E-Mail: dleblanc () iss net Atlanta, GA 30328 | www: http://www.iss.net/
