HERE'S MY PROBLEM;

TRYING TO IMPLEMENT A ONE-WAY TRUST BETWWEN 2 DOMAINS(LETS SAY A AND B) "A" IS RESOURCE AND "B" ARE USERS.
TRUST WORKS IF "B" TRUSTS "A", BUT NOT IF "A" TRUSTS "B". YOU GET MESSAGE THAT TRUST RELATIONSHIP BETWEEN PRIMARY DOMAIN AND THE TRUSTED DOMAIN FAILED. WE HAVE TRIED EVERY ORDER OF ADDING IN USER MANAGER FOR DOMAINS, HAVE USED DETDOM.EXE, HAD MICROSOFT ON THE PHONE. THERE IS NO HARDWARE BETWEEN THE 2 DOMAIN CONTROLLERS. THEY ARE PLUGGED INTO THE SAME HUB, AN HP. ANY CLUES THX

You have to do it in the correct order....

true. on a pc within trusted domain you specify the trusting the close userman.
from pc in trusting you specify the trusted using the same password and close user man.
the correct administrator rights reqd throughout.
