Question : Certificate Authority Autoenrollment

I have followed the instruction of applying autoenrollement for Certificate Authority. Though when I went on the laptop, I did not see any new cert. I checked the group policy, it seem that I received the latest policy.

Do you know how to check whether or not laptop has received a new cert using autoenrollement?

Answer : Certificate Authority Autoenrollment

Try following these instructions to the letter: http://www.microsoft.com/technet/prodtechnol/windowsserver2003/technologies/security/autoenro.mspx (or more detailed: http://technet2.microsoft.com/windowsserver/en/library/c25f57b0-5459-4c17-bb3f-2f657bd23f781033.mspx?mfr=true )
BTW, check that client PC is member of the domain and that the machine is in the OU on which you deployed the GPO (not necessary when you did it on the default domain policy).
