    I started getting this message in the System Event Log about a month ago on
    our DC. Nothing had changed on the server around this time and everything
    seems to be working. The server is the only DC and DNS server in the domain.

    Computer: FILE1
    Source: LSASRV
    Category: SPNEGO (Negotiator)
    Event ID: 40961
    Description: The Security System could not establish a secured connection
    with the server DNS/file1.mydomain.internal. No authentication protocol was
    available.

    Any suggestions for resolving this error are appreciated.

    Thanks,

    Mike

    Do you have Reverse Lookup Zones set up? This can happen when you try to
    register PTR records, and don't have reverse lookup zones.

    If not, check the other logs to see if there are any other warnings or
    errors occuring at the same time.

    Reverse Lookup Zone for the subnet is configured and correctly populated. No
    other errors in any of the event logs.

    This error has been written to the log once per hour since it started to
    occur.

    Thanks,

    Mike

    What is the IP address of the DC and what are the Primary and Secondary DNS
    IP's?

    The IP address of the DC is 192.168.205.14 (subnet 192.168.205.0/24) and
    Primary DNS is currently set at 127.0.0.1, although I have tried
    192.168.205.14. Secondary DNS is blank.

    Thanks,

    Mike

    Re-entering credentials for DNS dynamic updates registration in the DHCP
    snap-in resolved this issue.

    Thanks for your help!
