Error code: (null) (0x00080043)
I'm wondering if there is a way to change DR-1.corp.test.com to another Domain Controller. The domain controller DC-1 is not behind a firewall. Any assistance would be greatly appreciated.
the issue you are seeing regarding firewall ports are due to firewall ports on the client side. Perhaps there is a firewall up on the client, no?
One way to find out the root cause is to run some commands:
telnet corp.test.com <port>
If the telnet request fails, then it implies that the port is open. Otherwise, if you do not receive a failure message, it most likely means that the request is still attempting to connect via the port, which most likely a firewall is blocking the port.
Please let me know if this helps you out or if you have further questions.
