Failed to log on to Microsoft Dynamics - AX 2012

After finally managing to get the AOS to start using a Windows User account DOMAIN\AXAOS, I am no loger able to access AX 2012. I have installed the client on the AOS, tested as Admin login and my own user login from my PC and no luck with either.

Firewall is off on the AOS Server. The database is using the FeaturePack Demodata provided from the MS Website.

I ran the script on the SQL as per these instructions to change the AOS user.

If I go to Configuration I also get an error Unable to log on the Microsoft Dynamics.

SYSUSERINFO has one record with ID of Admin.

Any ideas?
