Hi Nancy,

Client can use any cached CRL as long as it is valid. You can erase it by
purging temporary Internet files. This will ensure that clients checks for
new one... The other thing you can do is design your Base and Delta CRL
interval to your needs.

There is no harm in deleting certificate that was revoked, but it is not a
must either. Imagine this was on a laptop and out of the office and user got
fired. You don't have access to the laptop so you can't erase it.

Once the client (PC) gets new CRL it will not allow use of that certificate
any more. You can also remove old or revoked certificate with group policy.
Open group policy at any level that you like (domain or OU) and under users
settings -> Windows Settings -> open security settings -> Public Key
Policies -> Autoenrollment Settings...

I hope this helps,

Mike
