We have an issue occurring on many systems in our organization. If a user does a system reboot while Hamachi is running, the system takes 5 to 10 minutes to restart. Often times the system will display a BSOD (Blue Screen of Death) error message.
Currently the only solution we have found works is to reboot again, open Hamachi and power off the VPN tunnel. Then most importantly, exit the Hamachi program completely and restart the machine. Once the machine loads, open Hamachi and reconnect to the VPN tunnel.
