Cannot Generate SSPI Context

Hi,
I have upgrade my windows 2000 to service pack 4
and when i leave the sql server idle for around 2 hours,
an error occur -- Cannot Generate SSPI Context.
Why this problem still occur since i have upgrade
to service pack 4. Is it i am wrong in the step while
trying to connect to the sql server or is it related to
the network logon window authentication problem?
Thank u very much.
regards,
