Failed to create a trust relationship between NT4 and 2003 AD

Dear all,

I got a NT4 domain with "SP3" only, would like to migrate its user
accounts (> 1000) to a new 2003 AD. Right now I have trouble on
creating the trust relationship between them.

I did the entries for both DCs on LMHOSTS file. I did the WINS service
and created the Static Mapping entries for the opposite DC.

My problem is:

I can't create the one-way or two-way trust relationship between NT and
2003 AD. On the NT4 PDC, I created a Trusting domain into Policy and
entered the password. But I can't create a Trusted domain and the error
said "Could not find domain controller for this domain". On the 2003
AD, I created a New Trust and the NT4 domain name can be recognized,
but failed into the last step and got this error on the validation.

"Verification of the trust between the domains was unsuccessful
because: Access is denied"

What my case is very similar with this link but even I disabled the
"Require Strong (Windows 2000 or later)" session key, the problem is
still existed.

I tried the below:

On the Network Neighbour I can browse into the NT4 domain with their
related computers from 2003 AD server. I still can do browsing into
2003 domain from NT4 DC server and listing their related computers, but
I can't access it regarding the trust relationship failure.

I even followed some case to find a "Restriced Anonymous" registry to
make it 0, but I can't find this entry into my server. Can anyone
help???!!!!!!!!!!! I'm exhausted to find the solution for this
problem. Please help!!!!!!!!!! Thanks a lot.

Regards,
ODBC
