A message comes up saying that something is using port 80 and it asks whether to disable any websites. It's a new server with hardly anything on it (and certainly no websites, I think) but in any case, when you click the "Yes, go ahead and disable" button, nothing happens - same complaint.
Has anyone had this before? Is it safe to use some command line tool to disble any process using port 80? Assuming I can find such a process... I suspect it's come from an installation of Microsoft Visual C++ 2012 Redistributable Package (x64) or Microsoft Application Request Routing extension for IIS, both of which FMS 13 says are required, so I can't get rid of them.
Many thanks for any help.
