We have implemented credential roaming for user certificates on our domain. Everything is set up per Technet in Certification Authority and Group Policy. User certificates are roaming correctly, but only on Windows 7 workstations. For some reason, our XP workstations (all are SP3), are not picking up the user certs from AD. I've verified that KB907247 is in fact included as part of SP3.
Can anyone provide some help on this issue?
