We are having a problem with a 2000prof machine. In Add/remove programs there is nothing there. When I tried to start the windows installer service it failed. I went to the event logs and can see the list in event viewer but cannot open any of the errors. While checking things through Explorer I tried to open the \winnt directory and saw no folders or files. I can open non-system folders and view the contents. I can open the event log remotely and open the individual logs. I can use the command prompt and list the files in the \winnt directory. I have performed a virus scan and came up with nothing. In the app event log I found Event system error 4097. Nothing else really in the logs that looks suspect. Ideas?
