Regular Windows 7 BSOD with Shrew VPN client
- by Junto
The Shrew VPN client appears to be a good alternative to the Cisco VPN Client on x64 Windows 7. However, since installing it I've seen fairly regular BSODs. Minidump attached:

Machine is a brand spanking new Dell Precision T5500.
Superuser appears to have several recommendations for the Shrew VPN Client as an alternative to the Cisco VPN client on 64 bit machines, so I wondered if anyone here has seen this problem and possibly found a solution to the problem?
I've decided to run the VPN client under Windows 7 compatibility mode for the moment (Vista SP2) with administrator privileges to see if it makes a difference. Oddly, the VPN doesn't necessarily need to be connected. I've noticed it when browsing using Google Chrome and Internet Explorer, usually when I open up a new tab.
If it carries on I think I'll be forced to shell out the 120 EUR for the NCP Client instead.
