IIS error - The process cannot access the file because it is being used by another process

Cannot start website with the following error returned:

• "The process cannot access the file because it is being used by another process"

Within the IIS Manager, check the bindings for the website that cannot be started and note the port(s) being used:

     IIS 6: Right click the website | Properties | Web site tab. Note the port number for TCP port and/or SSL port

     IIS 7 & 7.5: Right click the website | Edit Bindings. Note the port number for http and/or https

Open a command prompt and run the following command

     netestat –an

Check to see if any of the ports noted above are listening. If so they are being used by another application. Change the binding so that the website in question uses a different port(s)

For example; if port 443 is in use try 444 instead.
