A few weeks ago I had a request to setup a new WSUS server running on server 2012. The setup was easy, but once I had turned it over to our client systems group they were trying to figure out how to have it run on port 80 for testing purposes. By default WSUS on Server 2012 uses port 8530 for Windows Updates. They quickly discovered that modifying the bindings in IIS won’t work in this case.
To modify WSUS to use port 80 the wsusutil tool is the preferred method.
The tool is located in c:\Program Files\Update Services\Tools
The command to change the WSUS website to use port 80 is: wsusutil usecustomwebsite false
