system reboot

[User 38905]

Hi! I have written an NT Service to monitor an application execution. The NT Service detect properly when the application crashes (deadlock). In order to reboot the system I am using the API function ExitWindowsEx to reboot the system, but it doesn’t work very well. As a matter of fact, when I call this API function the system shows a blue screen and stay in this situation timelessly. The code that I am using (the shut down example from MSDN) is show below (I guess I have got the right privilege). Does anybody know how can I make the system reboot properly? Thank you very much for your attention. Sergio HANDLE hToken; TOKEN_PRIVILEGES tkp; // Get a token for this process. if (!OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken)) error("OpenProcessToken"); // Get the LUID for the shutdown privilege. LookupPrivilegeValue(NULL, SE_SHUTDOWN_NAME, &tkp.Privileges[0].Luid); tkp.PrivilegeCount = 1; // one privilege to set tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED; // Get the shutdown privilege for this process. AdjustTokenPrivileges(hToken, FALSE, &tkp, 0, (PTOKEN_PRIVILEGES)NULL, 0); // Cannot test the return value of AdjustTokenPrivileges. if (GetLastError() != ERROR_SUCCESS) error("AdjustTokenPrivileges"); // Shut down the system and force all applications to close. if (!ExitWindowsEx(EWX_SHUTDOWN | EWX_FORCE, 0)) error("ExitWindowsEx");
