Make sure all the network connections are working as they should ('ping' the .NET box and make sure it has consistent network communications). If the network is OK, it sounds like you might have some internal issues with your QM2000.net box. Mine takes a bit longer to load than a QM2000 PCI card would, but I've never had any kind of issues you mentioned.
If you haven't already, I recommend you contact Pangolin directly using the "Contact.." link on their web page. Provide as much descriptive information as you can (including the serial # of your .NET box). The folks at Pangolin are usually pretty quick to reply to technical issues.
Good luck, and please keep us posted on what you find out!
