just to clarify the "machine" part for Dennis: this means that some process is either running as "Local System" or "NT AUTHORITY\NetworkService" - this would typically be some service installed on the machine. It is then able to leverage the machine-account's credentials from AD to connect to resources in the network, such as to a share of your application server.

It could be anything, best thing would be to go to those machines and try to see what they are doing or set up a network sniffer and watch the traffic coming in from them. In summary, could be a virus or a worm, could be something else. joe -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Dennis Depp Sent: Sunday, February 27, 2005 1:40 PM To: ActiveDir@mail.activedir.org Subject: [ActiveDir] Computer Accounts logging onto servers I have a Sys admin who is seeing two computer accounts logging on to one of her applications servers. The computer account logs on with a logon type 3 and then logs off. This admin is thinking something nefarious is going on, while I do not. Does anyone know what might be causing the computer accounts to logon to an application server?
