SUP\WSUS error 2147500037

WSUS синхронизируется нормально, но стоит запустить синхронизацию из SCCM, начинаются ошибки:
-------------------------------------
SMS_WSUS_SYNC_MANAGER:
 WSUS Synchronization failed.
 Message: WSUS server not configured. Please refer to WCM.log for configuration error details..
 Source: CWSyncMgr::DoSync.

SMS_WSUS_CONFIGURATION_MANAGER:
WSUS Configuration Manager failed to configure upstream server settings on WSUS Server "sccm.xxxx.local".
Possible cause: WSUS Server version 3.0 SP2 or above is not installed or cannot be contacted.

Борьба с исправлением не помогла. Решил использовать самый простой метод начать все сначала:

1) Удалить SUP роль.

2) Удалить WSUS.

3) Перезагрузка.

4) Установка WSUS используя альтернативные порты: 8530, 8531.

5) Установка SUP роли. 

6) Перезагрузка.

7) Проверить идет ли синхронизация.
