Five years ago, I was a relatively early adopter of Microsoft Small Business Server (SBS) 2003. One of the servers I set up back then is still going strong today. However, the self-signed certificate that the server uses for SSL transactions was set to expire five years after creation, and we just reached that mark.
The easiest way to change the expiration date for your server’s SSL certificate is to re-run the CEICW. When you get to the page asking about the web certificate, create a new one:
Obviously what you put in the “Web server name” box should match what you had there before – the external hostname of your server. SBS will generate a new certificate, whose expiration date will be five years in the future.
Because third-party SSL certificates from GoDaddy and others are so inexpensive these days, there is little reason to continue using self-signed certificates in SBS. However, if you want to stick with a self-signed cert for more than five years, now you know how.
