I have just started getting this error in the event log. Can anyone shed some light on it for me please?

The currently selected KDC certificate was once valid, but now is invalid
and no suitable replacement was found.  Smartcard logon may not function correctly
if this problem is not remedied.  Have the system administrator check on the
state of the domain's public key infrastructure.  The chain status is in
the error data.

The server is running SBS 2003 SP2

Thanks in advance
