Seeing these in the security logs? Help!! - Seems to be

A Kerberos Error Message was received:
 on logon session domain\myUserAcc
 Client Time:
 Server Time: 23:15:16.0000 9/29/2010 Z
 Error Code: 0x19 KDC_ERR_PREAUTH_REQUIRED
 Extended Error:
 Client Realm:
 Client Name:
 Server Realm: MCHL
 Server Name: krbtgt/domain
 Target Name: krbtgt/domain@domain
 Error Text:
 File: e
 Line: 98a
 Error Data is in record data.

Also getting these errors when a users goes to a site:

Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Data.SqlClient.SqlException: Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'.


Sometimes it works and sometimes it does, seems abit random.  Restarting the DC sometimes helps.  We currently have two DC's, one is  2008 R2 and the other is a windows 2003.  Please help!
