We are on Windows 2003 AD Domain and want to allow user account authentication from DMZ to 2003 AD internal network. But when we try to join AD domain from the server in DMZ, we get an error message that states "The RPC Server is unavailable". I worked with the network guy and for testing purpose, he allowed any traffic between DMZ to the internal network and no traffic was being denied. So, we moved forward to next solution for setting up Ethernal and captured traffic from the server in DMZ when tried to join AD domain. We got one error in the Etherbak capture log that stated "STATUS_ACCESS_DENIED, Error: STATUS_ACCESS_DENIED". Can anyone tell me what is causing this issue?
