XP LAN Issues

[anonymous]

I have only a hand full of XP boxes on my LAN, mostly a
Windows 2000 LAN (no 9x or NT). Which the below does not
happen on my 2000 boxes, just the XP Pro's. After the
user's logon the the domain, about 2-3 hours later, there
connections are restricted from any domain resources. The
user can log off and log back on and all is fine.

Below are a few of the events written:

Event Type: Warning
Event Source: LSASRV
Event Category: SPNEGO (Negotiator)
Event ID: 40960

Description:

The Security System detected an attempted downgrade attack
for server DOMAIN\servername$. The failure code from
authentication protocol Kerberos was "There are currently
no logon servers available to service the logon request.

----------------------------------------
Event Type: Warning
Event Source: LSASRV
Event Category: SPNEGO (Negotiator)
Event ID: 40961

Description:

The Security System could not establish a secured
connection with the server DOMAIN\servername$. No
authentication protocol was available.

-----------------------------------------

Also, Event ID: 2022 and 3210

After doing a few google's and being unable to resolve, I
figured here might be the best place.

Thank's in advance.

When this starts happening are you able to ping the DC?

computername.
