I suspect your domain controller infected with Confiker virus. Check this KB article. http://support.microsoft.com/kb/962007 Thanks

Hello, in addition to the other use also some other AV program to check your machine. A service with that name doesn't exist. Make sure that all other domain machines, especialy DCs are healthy before going on with the following. As the infected machine is a DC you should disconnect it from the network asap and complete reinstall it. If this is the only DC in the domain use a backup from before this happened and restore it to that running state. Unfortunal you have to recreate any object in AD but better then having a effected DCin the domain. If you have multiple DCs you are lucky and can just disconnect it and if needed seize FSMO roles on another DC and run metadata cleanup. Then format and reinstall the server and add it again if needed as DC to the domain.Best regards Meinolf Weber Disclaimer: This posting is provided "AS IS" with no warranties or guarantees , and confers no rights.
