Enabling Services in Recovery Console
If your server rebooted and now won't start properly, it's possible that a critical service or device driver on it has become disabled and is preventing Windows from starting. If you can't even boot into Safe Mode, try using running the Recovery Console off your product CD and when you're in the console, use the enable service_name start_type command to assign a Startup Type to the service you think may be causing the problem. The possible values of start_type may be SERVICE_BOOT_START, SERVICE_SYSTEM_START, SERVICE_AUTO_START, OR SERVICE_DEMAND_START. You'll need to know what the normal Startup Type for each service should be, and for this information see Appendix A of the Troubleshooting Guide in the Windows Server 2003 Resource Kit, a collection of books that every IT pro should have on their bookshelf.
