A little over a year ago I enabled Microsoft Certificate Services on one of my servers for the purpose of creating code signing certificates. My intent was to allow a handful of people in my company to sign macros in Access and Excel so that users would not get security warnings when opening these applications. For the past year this has worked flawlessly. Now all of the Code Signing certificates are expired and I don't know how to renew them.
Is there a way to simpley change the expiration date so that all the certificates continue to work? Or do I need to create new certificates and resign all the macros?
