Hello, I keep getting the error: "Session setup failed because no trust account exists : Script - AD Validate Server Trust Event." on my active alerts on SCOM 2007 R2 with the machine account name of LTVIC017 and the trust account of LTVIC017$. What I'd like to know is how do I track this computer/laptop down? There are no accounts for this device in AD, and I don't want this computer on my network at all. We have rolled out new computers and workstations with new naming conventions, and this one remains. Unfortunately our network spreads over a few cities, so I need some help to try and locate this device. Any help would be great. Thanks. Ampletrix
