[vpn-help] Another report of Lost network connectivity Win7 x64

[baillard at cox.net]

Problem description: Fri 2010-04-23 Windows 7 lost internet connectivity without VPN software running, problem was traced to DNS failing to respond.  Problem temporary solved by unbinding the 'Shrew Soft Lightweight Filter' from the network adapters (wireless and Ethernet), then DNS lookups work again.  I have not attempted to disable the DNS Proxy Daemon service yet as mentioned in http://lists.shrew.net/pipermail/vpn-help/2010-April/003169.html .  The laptop receives it's IP addresses and DNS servers via DHCP, and no changes have been made to laptop other than April 2010 Microsoft Security Bulletins and normal McAfee VirusScan (provided by Cox.net) updates (VirusScan 13.15.117, SecurityCenter 9.15.175, PersonalFirewall 10.15.106).

Perhaps the Shrewsoft DNS proxy software has a certificate or other time sensitive component that has expired and caused these issues?
