My Windows 2003 Server worked fine for months. All of the sudden on Monday the default web site is "stopped" and if I try to start it, I get a message that says that it is being used by another process.
Why is this? we did not make any changes on the computer, there are no weird processes running and there are no viruses. The only thing I noticed is that it will start if I change the port to something other than port 80.
This Windows 2003 server has only 1 web site in it and has only 2 roles enabled (file server and application server), it does not have firewall enabled either. This problem happens even when the server is disconnected from the network.
