    I am looking for a method of correctly identifying Windows O/S Versions and Service Packs remotely. Here are my 
restrictions:
- Performed Remotely (not in same broadcast domain)
- No Admin Rights on Remote Box
- No Username/Password on Remote Box
- VERY Few Packets Generated (excluding TCP 3-way handshake)
- Ability to **AVOID** IDS Detection

You should put this list to the NMAP summer of code team, they're
currently looking at reworking the whole TCP fingerprinting / OS
identification module.

I'm guessing much of what you want is going to be restricted by the
'few packets generated' condition - especially if it stops you from
establishing a connection to a remote TCP port for long enough to get
a banner message.
I suppose you'd need to plug in a sniffer and do some calibrating at
home first.  Eg - get your NT4 server, and sniff traffic from it, then
apply SP1, repeat, apply SP2, etc... then look to see what's changed.
