Hello,

This is not a licensing issue.  The product is licensed and works fine unless the PC does not have full internet access after a few days.

Back to my original question, do you know what IP addresses or servers on the internet QuickBooks Desktop is trying to get to?  As long as the PC has full internet access it works fine, but we can't allow the PC to have full internet access at all times, so I need to know what IP address or servers QuickBooks is trying to access so we can allow access to them on our company firewall. 

Thank you.
