Разрабатываем сабжевый DLL. (VС++ VS 2005) На локальной машине (без ввода login/pass) процесс создаётся. На удалённой не хочет. IWbemServices::GetObject() выбивает ошибку 80070005 - Access is denied (если не ошибаюсь), хотя указываю реквизиты администратора, и ConnectToWbem выполняется успешно. В чём причина? Я поначалу искал в значениях флагов CoInitializeSecurity(.., RPC_C_AUTHN_LEVEL_xxx ,..) и CoSetProxyBlanket(...), но безуспешно. Могет сталкивались? Что посоветуете? Листинг DLL | Код |
