The server is used as an SAMBA AD DC for a small network of users.
While in my lab, I could SSH to the box as expected but some some odd
reason, once deployed on site I can no longer SSH from the outside.

I assume you mean that you cannot connect to the server using SSH from the Internet via the client's LAN-Internet router.

Can you ping the server from the LAN?

Can you connect to the server using SSH from the LAN?

If you reconfigure the router to send incoming Internet SSH connections to another LAN host with known good sshd, can you connect to that host using SSH from the Internet?
