Re: IIS can not start - port 80 has been used by other application

run on the command prompt:
netstat -ano

It will output a line that looks like 0.0.0.0:80 <PID>

Use Task Manager to find out the process name of that PID (configure Task
Manager to show the PID for a process).

You should know what to do with a given process name.

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.
