Medisoft Error 6420--Networking Problem?

[Computernerd22]

Can you ping it? Also, what do you have for security setup? Perhaps, a firewall? If so, it could be the culprit. I had this problem at a doctors office I do IT for them and they were having the same problem but the issue got resolved. full story can be found here http://antionline.com/showthread.php?t=275531

6420 Error Troubleshooting Information

Point of Success uses the Advantage Database Server to protect data from network-induced problems and to speed access to the data. Point of Success software must discover the database server. To do this, a message is sent across the network to the other computers. The database server computer responds with information to allow Point of Success to connect to the database server. If this response is not received, the 6420 error is generated.
A 6420 error is always caused by a network communication problem. All of the resolution suggestions here deal with correcting communication issues.
