Description:
Issue
If you deploy a TDR Host Sensor to a virtualized Windows system hosted by a Scale Computing HyperCore environment, the TDR network driver might cause the Windows OS to crash.
Workaround/Solution
The TDR Host Sensor will not load the network driver if you disable these functions on a global level: § Allow Host Sensors to Cache Process Connection Metadata § Enable Kernel Host Containment Action For instructions, see Configure TDR Host Sensor Settings. For environments with mixed virtual and physical computers, WatchGuard recommends you create a Host Sensor group for the physical computers, and override the Host Sensor settings to re-enable these settings.
