Tnx....I tried both ways and they helped me. But I have bigger broblem here.....I have old server running NT4.0 and new server running WIN 2003 Server Standard Edition X64. I want to transfer user accounts from old server into the new one. I understand that MS, our god, don't offer compability between these two OS. So I did this......I installed another NT 4.0 to test PC and told him to play packup role. With this movement, I had user accounts whitch I can damage with no harm. Then I disconnected those two machines and told to packup server to play primari domain controller role. Then I upgraded NT4.0 on the test PC to Win Server 2000 and upgraded OS again to Win2003 Server Standard Edition. Now I have user accounts in 2003, but they are in my test PC. I'd like to transfer them into my new server running WIN 2003 Server Standard Edition X64, but I dont know how to do this. I tried to to this like I did with NT4.0, but no success-I told to new server to play packup role and he did. User accounts are in new server, but if I told him to play primary role, then he shouting, that he can't find accounts. Can anyone explain me how to do this right?
