Windows server - run nginx on port 80

Question

Is there any way to get nginx running on port 80 on a windows 2003 server? It seems that the http.sys service is running on port 80 which is the new "preferred way" for a web server to run on windows however nginx and apache don't yet use this. Is there an easy way to stop this?

When I try and bind to port80 i get the following:

nginx: [emerg] bind() to 0.0.0.0:80 failed (10013: An attempt was made to access a socket in a way forbidden by its access permissions)

netstat shows

Proto Local Address Foreign Address State PID TCP 0.0.0.0:80 0.0.0.0:0 LISTENING 4 

and that pid is

C:\nginx-1.2.5>tasklist /svc /FI "PID eq 4" Image Name PID Services ========================= ======== ============================================ System 4 N/A 

Answer 1

Turns out it was not http.sys and was in fact Sql Server Reporting Services... Disabled them and it was good to go.
