Have attached dcdiag and netdiag results.  The three remote sites are connected via AT&T WAN to central office.  Can successfully ping all server's DNS names from each server.  Ran DNSlint report and all Domain Controllers were successfully identified, found and resolved to correct IP addresses.

Run a netdiag. Make sure your RPC services are started.
