The problem faced, when it is not run from Denver at the start of the Apache wail that port 80 is busy. Denver outweighed a different port, but that's not the point.
netstat-ano says "TCP 127.0.0.1:80 127.0.0.1:60976
port is changed periodically, and the process with pid ω 4 – system.exe.
Actually, the question is: why system.exe takes port 80, and how to cure it?
was not happy :(
Upd: Sorry for the mistake, not System.exe and just System.
