netlogon error 5774

From http://support.microsoft.com/support/kb/articles/Q259/2/77.asp

In general, these error messages are logged because the Netlogon service does not receive a "success" message from the DNS server that owns the zones of the records that are being registered. There are several reasons why the Netlogon service does not receive a "success" message:
Domain controller configuration: DNS server entries in the Transmission Control Protocol/Internet Protocol (TCP/IP) properties of the domain controller are not properly configured.

Connectivity: This domain controller does not have Internet Protocol (IP), or Transmission Control Protocol/User Datagram Protocol (TCP/UDP), connectivity to the DNS servers that own the zones to which recordsneed to be registered or deregistered.

DNS server configuration: The DNS server cannot accept dynamic updates or is not configured to accept dynamic updates, as described in the Request For Comments (RFC) 2136 specification. If the DNS server that is used by the domain controller is not authoritative for the zones to which the Netlogon service is attempting to register or deregister, the DNS server must be able to provide (to this domain controller) the IP address of the DNS servers that are authoritative for the affected zones.
