Here's a handy command you can use on windows to list all of the open TCP/IP ports:
netstat -anop TCP
Need to list open UDP ports? You guessed it, try this:
netstat -anop UDP
Quite handy when you want to see if a program did indeed bind to a port. It is essentially an easy way to port scan yourself on windows.
This command is built in to windows, but there are some third party tools such as Foundstone's
fport.exe which also shows which program binds to the port.
Want to know if IIS is running in a 32 bit or 64 bit mode on a 64 bit server? Run the following command to determine this:

If you are running in 32bit mode on a 64bit server, then the output will look like this:
