You can try having users B,C and D map a share in the other domain by providing user A credentials, but since there are no trusts, all bets are off.

NET USE X: \\OUHSD_SERVER\OUHSD_SHARE /USER:OUHSD\USERA password

I can't try it over here because all our domains trust each other in one way or another. The closest I could get was to log on with an account from an untrusted domain onto a machine that was joined to a domain that trusted the untrusting target domain. *whew* If you followed that one - hat's off to yeh ! And it worked fine !
