Searching for the existence of the inetpub or wwwroot folder would do the trick.

Code:

$IIS1 = Exist ("c:\inetpub")
$IIS2 = Exist ("d:\inetpub")

Select
	Case $IIS1 = "1" OR $IIS2 = "1"
		?"ISS found"
	Case $IIS1 = "0" AND $IIS2 = "0"
		?"IIS not found"
EndSelect


Just expand with $iIIS3, etc... for more local drives.
