IIS and Skype : IIS: The process cannot access the file because it is being used by another process. (Exception from HRESULT: 0×80070020)
I just came back from work few hours ago. and i received a call from my PM about some issue, and it was on a web application running on HTTPS (SSL). so I tried to create a local application with SSL in my local IIS for testing purpose. ( to know how to create SSL sites in local IIS 7 see here.
well everything went well but I couldn’t start the HTTPS site because i got the following error:
After some Google search, and tracing my ports through netstat, i found out it was caused because of Skype. if you have Skype installed here is the way to resolve it.
All you have to do is go to Skype –> Tools—> options.
And under Advance tab click connection and you will see a screen similar to picture below. just deselect the highlighted option and save and restart your Skype. And start the SSL site in IIS. That’s all you’re ready to go with your SSL site through https://localhost.
