When using SalesLogix web it is often a good idea to run each portal in a separate Application Pool.  For a number of reasons we may want to find out what Application Pool is associated with each W3WP.exe process.

To find this out, simply open a command prompt via the Start Menu -> Run -> cmd.  Then type in "cd C:windowssystem32" and "cscript.exe iisapp.vbs" to see each W3WP's process ID and Application Pool ID.
