Symantec Network Threat Protection is causing Clients to hang after Windows Updates

After the windows updates were pushed out yesterday users are unable to login to their computers after rebooting (hangs on loading computer settings during login).  The 'fix' is to login with a local administratior and then the Symantec Threat protection box will appear asking if the change to the 'NTKernal' is valid.  I hit 'yes' and reboot and then users can login fine.  Obviously with several hundred clients on our network this is anything but ideal.

I'm also concerned about this happening over and over again with future windows updates.  Any thoughts or recommendations?

I would create a new client installer package and omit the Network Threat Protection as this seems to be a huge problem in corp environments. You can the reinstall the package as a silent install and push it via share and batch file. This way you don't have to worry about the NTP. Otherwise, check with the symantec forums.

Thanks for commenting, didn't think I'd get a bite. ;-)  Actually i have posted the exact question on the Symantec forums at the same time I posted here and got nothing there as well.  Removing Threat Protection does, of course, work to alleviate the issue, but was hoping for a solution that allowed me to keep the functionality.  It may well be what I end up havibng to do though.

I'll go ahead and accepty and close this just because it doesn't look like there's likely to be many more comments offered.  Thank you for taking the time to consider the question.

No problem. I know it is unfortunate that this product is so secure but it truely affects a networks overall performance. I allowed DNS and DHCP, etc and still had issues with some file sharing and even connectivity. This was the best solution that worked for me in the long run as there are other devices on that network that easily made up for the loss. Glad I could help.
