Winlogon.exe issue



Dear all,

We have intalled a network logon system based on smart cards. We use a Smart
Card (and CSP) with a digital certificate inside to boot up the PC's.

Some times, in different PC's and with no apparent cause or action with the
smart card we get an error from the winlogon.exe process that conducts to a
reboot. These exceptions didn't happen before the smart card winlogon
installation.

All the information we get is that there is a problem with the winlogon.exe
process, but we don't know if it is a bug in the OS caused by using smart
cards to boot up the PC's or if it is our software (CSP or GINA) which is
causing the winlogon process to fail. No debugging is possible because the
problem can not be reproduced and the PC is rebooted automatically after
clicking Ok in the alert window.

As I mentioned before, the exception may happen without accesing to the card
(neither physically nor through any software), just working normally with a
MSoffice aplication, for example.

We have no idea of what may be going on.

Has anyone notice this issue before?, Is it an OS bug or may be our software
that is causing the winlogon process failure?, Any idea?.

Thank's for any clue.

Best regrads

Fer
