Can't start site in IIS (use by another process)

Question

When I try to start a site in IIS it says:

the process can\'t access the file because it used by another process

I searched in Goog

Answer 1

In order to get more meaningful information, one way is to also get ownership information when issuing netstat so that you know the process which is using either 80 (default http binding) or 443 (if https binding is defined):

 netstat -ab

In my case the culprit was vmware:

TCP 0.0.0.0:443 ComputerName:0 LISTENING
[vmware-hostd.exe]

netstat can be piped into find to search for ports 80 or 443 (e.g. find ":443"), but these particular active connection will show at the beginning of the list at they are easy to see.
