Then update the “Admin” user’s SID, Network Domain, and Network Alias with your info in SQL. This SQL command will show you the info you need. This works in both 2009 and 4.0, but I’m not sure if the table’s field names have changed at all for 4.0 but it’s similar.
select ID, name, sid, networkdomain, networkalias from USERINFO where ID = ‘Admin’
After you update one user and are able to successfully login to AX, you can just disable all of the other users, then change their domain from the AX form, then re-enable them to automatically get their correct SID.
