[MS4W-Users] Install on new system issue

OK, so here is the answer to my question:


Irritatingly, Skype can switch to port 80. To disable it, select Tools > 
Options > Advanced > Connection then uncheck “Use port 80 and 443 as 
alternatives for incoming connections”.

What’s Using Port 80?

Further detective work is necessary if IIS, SSRS and Skype are not to 
blame. Enter the following on the command line:

netstat -ao

The active TCP addresses and ports will be listed — locate the line with 
local address “″ and note the PID value.

Now right-click the task bar and select Start Task Manager. Navigate to 
the Processes tab and, if necessary, click View > Select Columns… to 
ensure “PID (Process Identifier)” is checked. You can now locate the PID 
you noted above. The description and properties should help you 
determine which application is using the port.

This might be useful to put in a FAQ for MS4W.

Hope this helps,
