ProblemA BSOD is displayed and Netguard.sys is marked as the cause in the crash dump.
The server may also crash with a BSOD approximately every 12 hours.
CauseHP NC7781 NIC does not have the latest drivers installed; BSOD cause: Netguard.sys
The NC7781 NIC does not close connections when Netguard is used. When 100.000 connections are reached, Netguard will cause a BSOD and generate a memory dump. If Netguard does not crash, the server simply hangs, without a probable cause.
