IIS – ‘This Web site cannot be started. Another Web site may be using the same port’.


KB ID 0000660 Dtd 24/08/12


After being unable to access my Exchange Management console, it turns out the default website had stopped. When I attempted to start it I was greeted with this error.

This web site cannot be started


1. Nothing was using the usual web ports (80 and 443) which I found out by running the following two commands;

netstat -aon | find ":80"</p> <p>netstat -aon | find ":443"

Note: If you do have a process using these ports, it will be sown with its PID. To find out what that PID is, right click your Task bar > Launch Task Manager > Processes Tab > View > Select Columns > Turn on the PID column > locate the PID and investigate.

2. My problem was there was a 'Binding' to https that had no information in it? Right click the website > Edit Bindings > here you can remove any spurious entries. (Warning: if you're unsure, document any binding before you remove it - just in case).
