«Параметры конфигурации для ADUtil недействительны!» из SharePoint при попытке удалить сайт

Я пытаюсь удалить сайт на своей виртуальной машине MOSS и получаю следующую ошибку:

Configuration settings for ADUtil are invalid!

То же самое при попытке восстановить сайт поверх существующего с флагом перезаписи. Не могу найти никаких ссылок в Интернете.

Полная трассировка:
