IIS 6.0 default web sites not starting port 443 problem.

I just installed Exchange 2003 SP2, buyed a valid SSL, configured all the permissions needed for OWA, but when I try to start the default website, I get an error "The process cannot access the file because it is being used by another process."  , I don´t know what other program is using the Port 443, because if I change the port to another one, it will start....
I get this errors: w3SVC error 1004:
Cannot register the URL prefix 'https://*:443/' for site '1'. The site has been deactivated. The data field contains the error number AND HTTP error 15005: Unable to bind to the underlying transport for The IP Listen-Only list may contain a reference to an interface which may not exist
on this machine. The data field contains the error number.

Can anyone help me?

Check this KB.


Good luck
Check the IP address of Default Web Site.. If it is running on any specific IP change to "All Unassigned". You can also try viceversa.

I configure to use port 442 and everything works ok, so for sure another program is using port 443 (svchost.exe), but how can I find out which one it is?

run netstat -ano in command prompt to check. Note down the process id and check in task manager.

I found the problem!!!
using netstat -ano, I knew that svchost.exe was using that port, algo I found out that EventWZCSVC was using port 443, I google it and fould that a service called "Windows Zero Config" or something like "Wireless Sistema" (my OS in on spanish), I stopped the serice and everything´s working...
