assistant: Nope, as follows:
DOMAIN NAME:         COWBOYCOUNTRY
COMPUTER NAME:       OLDRED
COMPUTER USERS NAME: Old Red
You'd have to of known Old Red. Finest toughest and oneryest hired hand in
the west. Taught John Wayne everything that John Wayne ever knew about
Cowboying.
Any way, Old Red is setup on the DC with the Domain user Account  "Old Red".
He is also setup on the local NT wks computer's User account base as "Old
Red". Don't know if you've noticed it, but when you log on to Windows NT, you
can choose what domain log onto or a local account. In this case using the
above naming, if user name "Old Red" logs on from domain COWBOYCOUNTRY then
he gets the domain users profile. If Old Red logs on from the local account,
"Old Red" from "\\OLDRED" then he gets the user profile for old red that is
on the local computer, which at this point in time is completely different
than the domain users profile.
As far as cached security, it wouldn't be too hard to test, but I never have
as all shared resources go through my PDC. I can't imagine that cached
security would work either in Windows 95 or Windows NT if the resource
sharing is setup to be in a domain and user level (not share level). With
both Windows 95 and Windows NT,the domain controller has to verify that the
user has a valid user account and that is done for what I think are obvious
security reasons. I just can't imagine that MS would be so niave as to allow
a cached security account on a workstation with domain security setup. That
totally would defeat the purpose of domain security as you would then be back
to a individual machine/user base share level. I would also hope that if MS
did infact allow workstations to used cached domain security, they would have
sense enough to warn about it somewhere in the DOC's.
