Source:Service Control Manager
Forefront TMG Client Agent terminated with service-specific error. 2147942632(0x800700E8)
The issue may be caused by DeviceLock access control permissions settings blocking access to WiFi to currently logged-in user and SYSTEM accounts.
Provide user and SYSTEM accounts with Full access to WiFi.
In case it is still essential to block access to WiFi, we recommend to disable WiFi adapter in BIOS where applicable.
