IP-based AUTD failed to initialize. Error code: [0x80004005].
This error is somewhat critical and will probably prevent any mobile device that uses ActiveSync from receiving push notifications (see also event 3015 from same source). The installation of patch 951746 and/or 951748 causes this problem as soon as you reboot, a result of enhanced security for DNS. To resolve this problem, see the additional links below - or - as a quick fix - navigate to this registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters and edit the "ReservedPorts" value by ADDING the following lines: 645-1646 1701-1701 1812-1813 2883-2883 4500-4500 This change requires a reboot, and the fix resolved our problems immediately after the reboot.
