I am using IIS 5.1, and it is set to listening to port 80. Now IIS
does not start when I reboot and login using my user profile. I can
not start it manualy either. It shows "Unexpected error 0x8ffe2740"
consistantly. This is not happen when I use Administrator to reboot
and login.

I found that another application already running on 0.0.0.0:80 local
address if I am using my profile.

If I login as Administrator, the 0.0.0.0:80 is not used and IIS is
running fine.

How to check which application is using that local address and port
80? I have uninstalled few software (PHP 4.1, MySQL) that I thought
may causing this problem, but could not help.

Please help. Thanks.
