Les -
We currently are running in pre-Windows 2000 mode as confirmed by group 'Everyone' in the 'Pre-Windows 2000 Compatible Access' built-in group.

Seeing as the INGROUP not working well for me and Win9x and the Win2003 server, I went another route to try ENUMGROUP. Odd thing I have found with ENUMGROUP is results obtained.

This is listing of groups returned when logon script called at network logon (group-type added):
RATE CARD (Global)
SYND CLIENT SVCS (Universal)

This is listing of groups returned when running same logon script from command line after logon complete:
MyDomain\RATE CARD (Global)
MyDomain\SYND CLIENT SVCS (Universal)
MyDomain\ACCOUNT SERVICES (Universal)
MyDomain\DOMAIN USERS (Global)
+ built-in groups EVERYONE, NETWORK, AUTHENTICATED USERS etc.

Membership in 'ACCOUNT SERVICES' is due to being member of SYND CLIENT SVCS - a nested group - which has worked fine in the WinNT domain.

Of course, it gets me wondering why I get the different results. It is definitely Win9x specific - my XP box returns consistent results when run either method. Dumping the Win9x would resolve my issue but not possible at this time.

Anyone with ideas - I'd appreciate hearing from you.
