Sometimes, firewall programs just don’t seem to talk nice with programs you need to use. For instance, I’ve had two clients who have had issues with McAfee recently where they need to download a removal tool right from McAfee’s web site in order to “properly” remove the program (kind of strange that you would need to have a separate program just to remove it).
If you have connection issues with your QuickBooks Point of Sales client; check your firewall program…it just might be the culprit. If you have McAfee, here is the URL for the removal tool. Once you are done with that, don’t forget to add all the ports that you need opened in windows firewall so that you can connect your client POS to your server POS.
