I have a 2 way trust between a Win NT 4.0 Domain and a Win2K Domain.

I'd like a user with a user account from
"Domain_A" to be able to log into
"Domain_A" from a computer on "Domain_B"" (from the "Domain_B" network)..

- "Domain_A" and Domain_B are on two physically different networks.

- [ Domai_ A, NT 4.0 ] <== 2 way trust ==> [ Domain_B, Win2K (Domain_A user
here) ]

- "Domain_A" user tries to log into "Domain_A" from "Domain_B"

This is what I've tried so far, but it didn't work (from the Windows login
box):
----------------------------------------
- user_name: < Domain_A\user_name >
- password: < password >
- domain: < Domain_B > ===> I selected "Domain_B" from the drop down
box...
----------------------------------------

Does anyone have any thoughts or ideas on how to make this work?
Thank you in advance for any and all help!
