So, if you’re trying to install DirectAccess on a 2012 server with certificate support for Windows 7 clients and during policy application it fails with “The RPC procedure call failed” check and see if you have any tombstoned or abandoned DC’s in AD. I just had a situation where two dead DC’s that were only showing in ‘nltest /dclist:’ prevented DirectAccess policy application.

Deleting the abandoned computer objects fixed the error. This managed to keep Microsoft PSS stumped for a couple weeks until Shannon Fritz noticed them during our 4th re-implementation.

Now, on to testing!
