It seems that Simply Accounting’s database manager will need to be allowed through the Windows Firewall with Advanced Security:
When we look in the Windows Firewall log we see lots of dropped packets:
The base connection port required is 13531:
While that port is listed in the dropped packets list, there are also others. So, we need to make an exception for the Simply Database Manager program as well as others.
Once the rules were created we restarted the Simply Accounting Database Manager in Services.msc we were able to make a successful company file connection to the server.
We will also be setting this configuration into our GPO linked to the Computers OU so that any workstation or Remote Desktop Server will not get hung up on Simply connections.
