I have a windows 2003 server running an L2J gameserver.

We are getting this windows "Event" warning once an hour, which is causing conection reset and mass disconnect to all players online.

Event Type: Warning
Event Source: LSASRV
Event Category: SPNEGO (Negotiator)
Event ID: 40960
Date: 1/25/2008
Time: 12:39:10 PM
User: N/A
Computer: CP
The Security System detected an authentication error for the server DNS/ns.noc4hosts.com. The failure code from authentication protocol Kerberos was "There are currently no logon servers available to service the logon request.

This event is occuring exactly once an hour, windows would freeze on me for 30-60 seconds, the connection would reset, when I check the game console, all players would have been disconnected !

The L2J developer working on the gameserver is 99% sure it has nothing to do with L2J.

The hosting company support, took down the server for 2 hours and did a full hardware check and ran a full diagnostic but found nothing !

I searched the internet about the issue and all I can find is that its DNS related and im no DNS expert !

If you are a windows 2003 server admin and would like to take a look, be my guest and pm me. Any help or advice is really appreciated.
