Merging two NT4 domains

Two companies having their own separate (NT4) domains "A" and "B" were merged together. We created new users, some with the same name on both domains but with different shares and rights. Later on we established two way trusts between both of the domains, now we have decided to merge both domains.

I am very confused and need help.
How can I merge two Domains? There is no Windows 2000, NT4 environment only.
How can I move users to other domain where the same name with different rights exists?
Does any one have experience doing it?

Would appreciate any help in this regards,
Thank you,

Sound like its a mess. As what you said W2k is not an option, In my opinion W2k is the perfect solution and implement OU between company and set each individual permission

Now, to merge the 2 domains into one, these are the steps:

1. Decide which domain will remain. Only one of the domains can stay.

2. Create new accounts on Domain A to replace the accounts that will lost when Domain B is deleted.

3. On domains that trust Domain B, remove that trust and make them trust Domain A. (See the Microsoft Windows NT Advanced Server "System Guide" for details.)

4. On Domain A and all trusting domains, change Access Control Lists (ACLs) to replace references to the accounts on Domain B with references to the new accounts created on Domain A.

5. Move all workstations on Domain B to Domain A.

6. Demote the domain controller of Domain B.

7. From the Server Manager of Domain A, remove all servers from Domain B (if they are still listed as members of Domain B) and add them to Domain A. Make sure the domain name on all Domain B servers are changed to match the name of Domain A.

8. Start the servers that had been in Domain B. Allow enough time for replication from Domain A to take place, and then check the event log of each server to make sure each server successfully imported the account databases of Domain A.

Got this from Technet article Q112372:

The only difference for you in the above steps is Step 2. You will use ADDUSERS to create the user accounts.
