How to Determine if IIS is running in 32 or 64 bit mode

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:

cscript adsutil.vbs c:\inetpub\adminscripts\ GET W3SVC/AppPools/Enable32BitAppOnWin64

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