Hi,
i did some months of research because I love WinGate and I always want to use it with enabled ENS driver. In virtualized environments like VMware and Parallels with ACPI-enabled (All Post-XP Windows) it's impossible to run WinGate with enabled ENS driver without getting a BSOD after a few minutes or hours. I've also tested WinGate 7 and 8.
In ACPI-disabled environments (adding the parameter monitor_control.disable_apic = "TRUE" in the configuration file for the Virtual Machine and choosing the Non-ACPI-HAL at the initial stage of the XP Setup) this BSOD won't happen. On Vista and Win7 (On these versions of windows it's impossible to disable ACPI) it doesn't happen too, when you disable the ENS driver.
