Quickie post – I’ve ran into a handful of servers since SBS2008 that have their Sites certificate expired and this results in a handful of event log messages and other annoyances. It a customer actually uses the Sharepoint service built-in, obviously the site won’t work properly using HTTPS because … well, the certificate is expired.
Reissuing this is pretty easy using the following steps:
- Open the IIS Manager on the SBS Server
- Click on the server name in the left-hand side tree (see image @ #4)
- Double-click SSL Certificates, which opens that section
- Click New Domain Certificate as shown:
- Enter information on the certificate noting that the Common Name should be Sites:
- On the next screen, select the Domain’s certificate authority and enter a friendly name:
Note: To my knowledge, all SBS services come with AD Certificate Services installed, which is the basis for this whole article
- The certificate is now available to IIS. Review your IIS Site bindings and move any sites using the old Sites certificate to the one you just creased.
- Don’t forget to delete the old Sites certificate off the machine or you’ll get warnings in your Application log about it being expired.
