проблема с терминальным сервером 2003 в домене

Добрый день. Помогите с проблемой. Есть домен 2003, в нем терминальный сервер 2003. Пользователей периодически выбрасывает из терминала, повторно можно зайти только после перезагрузки. На терминале регистрируются ошибки Browser 8021 и 8032, и userenv 1030. Но DNS работает нормально. Dcdiag и netdiag на контроллере домена не дают ошибок. Вот результаты netdiag с терминала:
