More auth issues: 0xc000006d on Windows 2008 R2

Next on the schedule of problems we had an issue with again, with everything working fine remotely and not working when running locally. This time, it didn’t take as long to figure out what was going on, the root of the problem was “Account failed to log on (0xc000006d)”, and the explanation for that is here:

The basic idea is that you can’t authenticate against the local server using anything except the local server name.

And it still didn’t work.

The server is Windows 2008 R2, and the documentation said that I had to set a registry key at: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0

That did not work, but what did work was setting the DisableLoopbackCheck at: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa

No idea why, and if there is a problem at the documentation for Windows 2008 R2, but this is how I got it working on my end. I would probably like it more if I was able to use the recommended solution, and not the solution explicitly not recommended.

Any ideas?
