В хождении по сотни ссылок было найдена:
"нужно удалить Update for Microsoft Windows (KB948609) и перегрузить сервер"
Такого обновления у меня не имелось.
Поэтому пришлось делать так:
http://support.microsoft.com/kb/320202
1 удалить все .нет пакеты
2 затем удалить ISS
установить заново IIS
3 установить .net 2.0 + sp + 3.5 + sp
следим чтоб обновления KB948609 не устанавливались.(хотя так и не видел их)
4 затем удаляем Client Access Role
устанавливаем Client Access Role
5 отключаем ОА ставим RPC over HTTPS
включаем ОА.
+ у меня была такая ошибка в сонсоли
