Dial-In tab error "Dial-in page initialization failed" on 2012 and 2008 servers

I have a two-server environment with a 2008 and a 2012 server. 2012 is the only domain controller.
I cannot access the "Dial-In" tab in Active Directory Users and Computers. When I try, I receive the following error:

Dial-in page Error
Could not load the Dial-in profile for this user because: The network path was not found.
.

When I click OK on this error, the following is displayed:

Dial-in page initialization failed.

I have done Google searches on this error.
The permissions on the winreg and allowedpaths folders are correct.
The Remote Registry service is running.
The primary NIC is the first in the binding order.

I am not able to find any useful errors in the event log that indicate trouble with this, or any other trouble that might be related.

I installed the AD Remote Administration Tools on the Windows 2008 server, opened AD Users and Computers on that server, and I get the same error.
The DNS pointers are correct, including the domain suffix. I have no other indications of Active Directory lookup failures.

Update: I was able to use the following netsh command to get the job done for now, but I'd like to resolve this issue.
netsh RAS set user name=[username] dialin=PERMIT

Any ideas?
