I have a production application server running Windows 2003 on a Unisys ES3020L box that is having all sorts of weird issues. The RPC Server service (rpcss) won't start, so Net Logon service won't start. I logged in locally and opened the services window. It's empty except for a blue block in the upper left corner. I can export the list of services and they are all there (with automatic as start type for rpcss and netlogon), but they don't show up in the services window. I opened Event Viewer hoping for some clue, and I can see all of the events listed, but the properties windows won't open for any of the events. I opened a command prompt and tried to do a "net start rpcss" and I received "System error 5 has occurred. Access is denied.). The task bar at the bottom of the window does not have any applications in it, no matter what is open, I switch between windows using Task Manager. Yet with all of this, the production application on the server is still operating and serving users (with Apache). I ran a scan on the Windows Protected File Service to make sure that all of the protected files were intact. I checked the registry to make sure that the stopped services had Start = 2, which they did. Does anyone have any ideas what may have caused this mess, and how to fix it? All help is appreciated.
