NTLM group retrieval

[Jonny Larson]

Hello:
Is it possible to do dynamic group retrieval in an old NT4 domain via 
NTLM.  Does the NTLM protocol support anything like that?  Is it 
possible to retrieve group membership information from an NT4 domain 
controller?

To be clear, we are NOT using Active Directory.  We just have an NT4 
domain with primary & secondary DC's (and also WINS).

TIA,
Jonny L.
