I have only seen SAMR_GET_USRDOM_PWINFO (opnum 0x2c) when a Win2k
client joins an NT 4 domain.  Ooops, there is opnum 0x38
in the Win2k user password change.  Hmmm....should just return
a policy handle and a four byte return value.

Interesting though, I don;t see it being closed by the Win2k 
client....Hmmm....Don't see where the results of SAMR_GET_DOM_PWINFO
are being used in SAMR_CHGPASSWD_USER.

btw...what is the "MSRPC Authenticationm Verifier" that I see 
after the Stud Data in netmon 1.x?
