This message may be shown when trying to connect to a remote database from a workstation:
Note: The blank area in the error dialog above will have a machine’s name listed.
If this happens then it is likely an issue with the firewall settings on one (or both) machines.
For TaxCalc to connect to the database, the following ports need to be open through your firewall:
Note: Before getting to grips with firewall ports, you can try temporarily disabling the firewall entirely.
However, this test is entirely at your discretion – there is always an element of risk when disabling a firewall, even temporarily.
If the database connection can be made while the firewall is down, it is definitely a firewall problem. Once the firewall is re-enabled, opening the ports listed above should solve your connection problem. Guidance for your specific firewall should help you with correctly opening these ports.
