Я пытаюсь запустить приложение службы c# watchdog windows из этого потока stackoverflow
У меня проблема в том, что WtsApi32.WTSQueryUserToken возвращает false с следующее сообщение The operation completed successfully в этом фрагменте кода:
// Retrieve the active session ID and its related user token.
var sessionId = Kernel32.WTSGetActiveConsoleSessionId();
var userTokenPtr = new IntPtr();
if (!WtsApi32.WTSQueryUserToken(sessionId, out userTokenPtr))
{
throw new Win32Exception(Marshal.GetLastWin32Error());
}
После некоторой охоты я обнаружил, что общая проблема заключается в том, что привилегия SE_TCB_NAME должна быть предоставлена, но я не верю, что это быть проблемой, так как я запускаю приложение с правами администратора в режиме отладки, а код ошибки не соответствует типичному коду ошибки, когда SE_TCB_NAME отсутствует (ERROR_PRIVILEGE_NOT_HELD)
, если SE_TCB_NAME вопрос, можете ли вы предоставить образец кода для предоставления SE_TCB_NAME. Единственный пример, который я смог найти, был здесь , но для предоставления SE_TCB_NAME мне нужно запустить Impersonation.ExecuteAppAsLoggedOnUser("applicationName", null);, и я не уверен, какой параметр ввести для "applicationName" в контексте моих кодов, так как я в настоящее время запускаю процесс с ProcessStartInfo.
