have you looked at your firewall to make sure traffic from that server is being allowed out?


just getting exchange DAG connected to internet. As I had the old IP address on firewall NAT that was used for DAG which was not needed as it could just use the PAT and primary server has proper NAT that is entered in public DNS. I will have to try and complete and reboot this server and if still does not work the I will have to make call to MS.
