NT Server Password Reset and XP Workstation Digital Cert

Hello,

Just wondering if any of you guys have faced this issue.

NT Server requesting password change and after XP
Professional workstation updates password, the digital
certificate for IE 6 is no longer recognized. I am forced
to import the digital certificate.

Does NT Server password change change anything in the
user's profile which would cause this?

We have tried saving the digital cert automatically select
store and tried personal store settings and we are getting
the same issue.

Any help would be appreciated.

Sincerely,

John
