It's been awhile since we've used the LNV system and a lot of networking, security and firewall changes have been made since then.  When the system boots up, it get a message saying the gatekeeper has rejected the connection.  

I personally have never setup/configured the LNV system so I don't know what's "normal" and if this could be an internal config issue or something else.

I do know that the system has a static private IP address that is NAT'd in our firewall to a dedicated public IP address with no firewall rules applied to it.

SO, does anyone have suggestion to what might be causing this?
