Event ID 40960 + 40961 / SPNEGO

I am using Windows XP with SP2 and latest updates installed in an AD Domain, dc is a Windows Server 2003. The problem is that the user account has been automatically locked and am getting the below in the event ids:


Event ID: 40690
Type: Warning
Usre: N/A
Source: LSASRV
Category: SPNEGO (Negotiator)

Description:
The Security System detected an attempted downgrade attack for server cifs/SERVERNAME.DOMAINNAME.net. The failure code from authentication protocol Kerberos was "The user account has been automatically locked because too many invalid logon attempts or password change attempts have been requested. (0xc0000234)".

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.
