Shortly after a Windows 7 machine boots up, the error "Windows has encountered a critical problem and will restart automatically in one minute. Please save your work now." pops up and the machine reboots in a minute. This happens every time the machine boots up using Symantec Endpoint Protection (SEP).
SEP Application and Device Control coupling with Citrix offline plug-in causes services.exe to crash.
When ADC is enabled, sysfer.dll is injected into services.exe process. There is an issue with sysfer.dll. When the Citrix offline plug-in (CtxSbxHook.DLL) is also loaded into the services.exe process, the issue is triggered and services.exe crashes as the result. Since services.exe is a critical Windows process, Windows is automatically restarted.
This issue has been fixed in Symantec Endpoint Protection 12.1.1101.401. See Upgrading or migrating to Symantec Endpoint Protection 12.1.1101 (RU1 MP1) TECH187753
If SEP hasn't been installed yet, SEP may be installed without ADC until a fix is available.
