LSASRV Event ID: 40961

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,

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!
