Guest Brion Posted September 20, 2007 Posted September 20, 2007 Hi everyone, We've been periodically seeing the following error message on all 4 of our Windows 2003 DC/DNS servers: Source: LSASRV Category: SPNEGO (Negotiator) Type: Warning Event ID: 40960 Description: The Security System detected an authentication error for the server cifs/127.0.0.1. The failure code from authentication protocol Kerberos was "There are currently no logon servers available to service the logon request. (0xc000005e)". The error message only seems to happen occasionally, but this morning we lost DNS on all 4 servers. After rebooting all 4 servers, DNS is back. I have no idea why DNS bombed out, but I noticed the above error message again this morning and I'm wondering if it could be related? Thanks in advance! -Brion
