Dial Up error 720: Solution for Windows Vista Home Edition?


When I try to use a broadband usb pen ZTE Model MF636 HSUPA, I get this error 720 message. After going to the ISP assistance, they tried everything. They inserted all the data needed to make it function but always the same error 720 message. It seems to be a port problem. It seems this is due to the fact that this a 2007 PC, and every time we uninstall Wan Mini ports, Windows get the wrong version of the controler. There is a solution in Microsoft Support http://support.microsoft.com/kb/810979/en-us/ but it applies to Windows 2000 professional edition. Please, is there a solution for this error 720 that applies to Windows Vista Home Edition?

Thank you!
