SSL Certificate on SBS2011 Expiring , where to find it

Posted on 2014-04-10
Last Modified: 2014-04-10
Hi all,

I've recently taken over a server, SBS2011 with Exchange 2010, also running IIS. I received a notice from godaddy that an SSL certificate for the domain is expiring. This domain is externally accessible as well.

I've looked in MMC, Certificates, Local Computer, while I see other certificates that match certificates expiring at different times, I cannot seem to find this one in particular .

I'm beginning to think it is perhaps an unused certificate that is expiring, however I am hoping for some assistance on where else to check on my server to see if there is a cert matching it. (trying to prevent any kind of outage if it does expire and is needed!)

Is there any other places on the server I should check, or any suggestions on how to tell where the certificate in question is being used?

Thanks in advance

Run the following command from powershell to see all certs for local computer:

gci cert:\LocalMachine\My | ft notafter, Subject

On exchange powershell run command Get-exchangecertificate |fl and compare the expired certificate with valid cert.

thank you both...

gci cert:\LocalMachine\My | ft notafter, Subject returned 5 certificates, none matched the expiration date that is the one in question.

Exchange 2010 is running on the same server, do I need to run a different powershell for that command or is it the same as the server? I ran in the server powershell and received an error saying it couldn't find that command.

If the command returned no certs showing up as expiring on that date then it seems your assumption is correct.

Any certificate for use by Exchange would be in the local store, the absence of an expiring cert indicate this is not a cert expiring locally.

ok I answered my own question. Ran the exchange powershell and there is also no certificate there that matches the expiration date of the godaddy one in question...

yup any certificates installed on the local computer for machine use, will be stored under localcomputer\my

So once you scan that location, it will give you a complete view of all certs, no matter what application is using it.
