Selected Test Results (selected in 'Test Results' table below)
Everything including multiple domains.
What does not
Start as windos service. Wine doesn't currently implement windows service type functionality. But you can autostart it on login using the standard autostart setting in any distro.
What was not tested
Windows Service Features
Everything works except the windows service functionality. DynDNS shares the problem with other applications that have windows service functionality. Since this problem is not unique to DynDNS, it should be considered Platinum.
