I have a VPN connection between two cisco 4400N VPN routers to connect between a home and business network. The computers are running Vista Ultimate. I cannot ping between the two computers even if I pull all firewalls off--Windows and 3rd Party
antivirus program. The two computers are wirelessly connected through cisco 4400N VPN routers, respectively. Cisco says it is a Windows issue. The VPN worked, for one day, then crashed. We set all the permissions so they could access a QuickBooks
POS 9.0 database. Not sure where to proceed.
