This issue has been posted before but not sure if there is a resolution. I installed Smart Security BE v4 and all my networking stopped. After 2 hours with tech support, we were able to finally manually remove the application and load v3.06. Tech Support was thinking it was a Dell NIC driver. I proceeded to do a push rollout of 3.06 to two PCs. 1 worked and 1 failed like my laptop. In looking further at the configuration of the PCs, I noticed 1 had the Sonicwall VPN (not removed from our base PC image). So - does anyone have a resolution for this? I am going to uninstall the VPN, load ESET (version 4) and then reload VPN and see what happens in the meantime. Thanks in advance!
