ONE OF OUR REMOTE OFFICES TRIES TO ACCESS OUR LOCAL CARDBOX SYSTEM VIA A VPN CONNECTION. HISTORICALLY IT HAS WORKED OCCASIONALLY BUT NOW WE CONSISTENTLY GET THE FOLLOWING MESSAGE AFTER CONNECTING, WHEN TRYING TO OPEN CARDBOX:- CANNOT FIND SERVER NAME. NO SUCH HOST IS KNOWN. (HOST_NOT_FOUND:11001) At the same time the correct server name that it says it cannot find is displayed in the top lh corner of the panel. Any ideas?
You say two things: it works slow and it does not work.
In my opinion: If the Cardbox host is not found by Cardbox Client after connecting to your office by your vpn, that means on the server where your connection "enters" your office, there is no permission to see the machine on which Cardbox Server is installed.
Perhaps, if there is a permission and it works veeeery slow, but the security (firewalls, virus protection etc) is such secure, that there no capacity for normal talk between a server an an application.
If you know the ip address of your Cardbox Server, try to ping your server. See the result. If this is all ok, check also port permissions on all involved servers (3105!)
Already talked with your office system administrator? What was his opinion?
