Hi<br />
<br />
I have just started getting this error in the event log. Can anyone shed some light on it for me please?<br />
<br />
The currently selected KDC certificate was once valid, but now is invalid<br />
and no suitable replacement was found. &nbsp;Smartcard logon may not function correctly<br />
if this problem is not remedied. &nbsp;Have the system administrator check on the<br />
state of the domain's public key infrastructure. &nbsp;The chain status is in<br />
the error data.<br />
<br />
The server is running SBS 2003 SP2<br />
<br />
Thanks in advance
