Windows NT4 to 2000 migration

We are moving an NT4 domain to a new 2000 domain.

The old NT4 domain is called nt_domain, the new domain on a W2K Server is called Company.local.

I began by installing ADMTv2 and following the directions. I got Company.local to trust nt_domain but nt_domain does not find company (or company.local for that matter) when I try to reciprocate the trust. So basically old domain trusts new domain but not vice-versa as per instructions of the ADMT KB article # 260871.

On the event viewer in company.local, I get:

Event Type:      Error
Event Source:      NETLOGON
Event Category:      None
Event ID:      5721
Date:            5/2/2005
Time:            3:43:40 PM
User:            N/A
Computer:      TXLDC1
The session setup to the Windows NT or Windows 2000 Domain Controller <Unknown> for the domain NT_DOMAIN failed because the Domain Controller does not have an account for the computer TXLDC1.
0000: 8b 01 00 c0               &#139;..À    

I created the account for the company.local DC on the old domain as a server but not a BDC. On the old domain DC, I get the following in the security event log:

EventID 528
Source: Security
Type: Success Audit
Domain nt_domain
Logon Type 3
Logon Process KSecDD
Auth Package: Microsoft_Authentication_Package_V1_0

But when I try to add the new domain, I get the error that the domain controller for the new domain could not be found.

I believe that when I get this resolved, I would be able to set up the ADMT software properly to pull everything over.

    Hae you Set up DNS resolution fro your new Domain.
    NT4 still uses DNS as a means of resolving names, as well as NetBIOS.
    I would set up the DNS properly and then NT4 should be able to resolve it properly.

    I hope this helps !

    I have DNS set up on the W2K Server. Should I just change the DNS settings on the NT4 box to point to the W2K Server? Is that what you are suggesting? The NT4 server is using another DNS server. Let me know if that is what is suggested? Thanks!

    DNS is not required for this do however need some form of name resolution.  NT prefers to use WINS.  Are both servers pointing to the same WINS server?  Try that.

    Remove the machine account you added to the old domain and instead add the trust to the new domain, making it a two-way trust. This is required for ADMT as specified in the article you cite,;en-us;260871
