# Windows 7 port 80 problem

iistomcatwindows 7

I want to run Tomcat on port 80.

I changed its port on 80, it fail to bind.
I check IIS, it use 8080(I configured)
Then people said winrm share 80 with iis, I configured that, it used

HTTP = 5985

HTTPS = 5986

It fails.

And the 80 is used by nt-kernal/system, whatever that is?

Who is using port 80 and how I get it to work with Tomcat.

By the way, iis can work on 80. I think Windows 7 must reserve for it, but where it reserve.
