Certificate issued by AD Certificate Services Expired and won't renew, how to issue a new certificate?

Hi,

One of our internal web sites certificates expired so it can't be renewed

From the "Failed Request" folder:

"A required certificate is not within it's validity period when verified..."

So I need to issue a new certificate but I can't seem to find out how to issue a new certificate via a certificate request file from within out Active Directory Certificate Services Management Console. 

Anybody know how I would do this? Or am I looking in the wrong place?

FYI, the certificate was originally issued from this internal CA so it was done before, by a previous administrator.

Thanks!

John H.
