How to change the Domain name on server in Dynamics Ax

First of all, after change the domain name, you need to change three things because the Dynamics AX works correctly:

If SQL Server is installed on the server

1)  MS SQL Server logon service

            If  you change the domain name you need to change

2)  Dynamics Server$Instance Name logon service

3)  Server Database of Dynamics AX Server Configuration Utility

After that and restarting the services, you should be able to start the Dynamics AX.

If you cannot start it, you need to review some database things explained Below..

In case you change the domain on the AX server computer, you will not be able to start AX because you don’t have appropriate privileges.

In order to resolve this you need to find USERINFO table in the database and change the record with ID = ‘Admin’

You should update following columns: 

     1)SID – you should enter your Windows SID (this is enough but you can also change another two fields) 

     2)NETWORKDOMAIN – your domain name

      3)NETWORKALIAS – network alias (username)

After this you will be able to start AX as admin and to admin other users.
