I'm going to run the memory test and hard drive diagnostic to see what the issues could be. Do the above codes look familiar to anyone?

Most of the dumps are NETIO calls that end up in an SeAccessCheckFromState, with raw stacks showing vfilter.sys. You also have one more obvious crash showing vfilter.sys calling RtlUnicodeStringToAnsiString, and passing in an invalid address.

Given all of the crashes seem to stem from the use of this VPN driver, I'm going to tentatively say this one is being caused by said driver. You have the most recent version of that Shrew VPN software, it seems (2.1.5), so I'm not sure what to tell you other than to remove the software, reboot, and re-add it to see if the problem is just a bum install. If it continues, provide another set of .dmp files for us to look at if you would.

These were caused byt your vfilter.sys which is ppart of your VPN client software. I would either uninstall it or reinstall it
But rather think it is the cause, I really suspect Symantec/Norton Antivirus software that cause all of these. Stop 7F is potentially caused by third party firewall. And it is possible that it block your VPN. Please remove Symantec/Norton completely using this tool:
Download and run the Norton Removal Tool to uninstall your Norton product | Norton Support
If you need a BSODs free antivirus software, try Microsoft security essential and use the built in firewall:

Thanks everyone. My company actually isn't using the Shrewsoft software. We just got web VPN software from F5. I'll remove the Shrewsoft software and see if that cures my ills. Thanks for such a quick reply!
