The WSUS is installed on an new installed Windows Server 2003 Enterprise Edition With SP1. The "To do list" in WSUS administrator page said that: Check your server configuration One or more Update Service services could not be contacted. Check your server status and ensure that the Windows Server Update Service is running. Non-running services: SelfUpdate It seems that the SelfUpdate Service is a sub service of windows server update services, but how can I start it? or my system have some problem. I use sqlserver 2k with sp3 for the database of WSUS
