SBS Small Business Server Self Signed Certificate Renewal Period

Hi All,

I have noticed a change in behaviour for SBS Self Signed Certificates recently, specifically relating to the renewal period.

From memory, they used to renew for two years, however three recent renewals done on our client SBS servers have only renewed for slightly over two months. This has happened on both SBS 2008 and SBS 2011 servers, fully patched and updated to date.

Obviously having to remember to renew client server certificates every few months will become a hassle!

Has anyone else seen this and/or know why the renewal period has changed?

Thanks & Seasons Greetings To All from Melbourne, Australia!

SBS sets up a CA at the time it is installed. Then the "self signed" certificate is issued as a leaf when the wizard is run. While the leaf is issued for two years, the root (created when the OS is first installed) is a bit longer so it doesn't have to be renewed as often and so that a new cert doesn't need to be installed on clients when the leaf is renewed.. Based on what you are describing, my suspicion is that the root is about to expire, which would make the window between leaf renewal and root expiration only a couple months. It isn't something you'll need to keep doing every few months though. Once renewed, the root won't expire again for a few years (much like the leaf) so you'll be back to normal.

Hi Cliff, thanks for the explanation. Is there command or GUI available to show the expiration status of the root?

Thanks and regards, Brad.
