I was suffering for a ridiculous problem for last couple of days. Something strange (UFO??) was listening at port 8 of my local pc and I couldn’t run apache on port 80. So I was searching for the solution and suddenly found that Matt from wordpress suffered from exactly the same problem. its ridiculous and very annoying!

So I followed the steps Matt suggested in his blog post – I applied the following command at shell

netstat -a -o -n

Then I found that a process with PID 2160 is listening at port 80. I give the following command

tasklist /FI “PID eq 2160”

then I found that the criminal is skype!!! God knows why the hell skype requires to listen at port 80. Then I quit from skype and everything runs fine. After running apache, I restarted skype and it runs smoothly!
