What do you do in IIS if you get an error when trying to start your default web site?

What do you do in IIS if you get an error when trying to start your default web site and it says that it cannot be started because another web site may be using the same port?

For some reason I have IIS 6 and IIS 7 on the same machine. I seem to be unable to start IIS 7 but it seems I can in IIS 6. Yet, I am able to see c:\inetpub\wwwroot\iisstart.htm but I am not able to see a viable http://localhost

I would try to figure out which other process is using the port. Try executing this command from a command prompt:

netstat -ao | findstr 0.0:80

The output should look something like this:

TCP 0.0.0.0:80 MACHINE_NAME:0 LISTENING 1656

The number at the end (1656, in this case) is a process ID. Open Task Manager and click View -> Select Columns... Check the box next to PID (Process Identifier). You can then find the process ID returned by netstat and determine which process is using the port, and end it.

Alternatively, you can configure IIS to use a different port.

Do you mean:
netsat -abn
?

When I type
netstat -ao | findstr 0.0:80
the system kind of hangs

If I type netsat -abn the process ID column is missing. Why would that be? How can I make it present the process ID column?

(update) It looks like I spoke too soon. I am getting some results now
