We recently started getting EVENT 64's in our Event log. Which, normally, I would point to being a problem with the self-issued certificate for the SBS sites or the Exchange certificate for SMTP. But when I checked the certificates, I found that it is the "Code Signing" Certificate. How can I Renew this? Microsoft's documentation is confusing at best, and I am concerned that doing any of it on an SBS server could break it. Any ideas on how to fix this?
