I have a single Server 2008 Rs Enterprise. It's running Exchange 2010 Enterprise. This morning I received a message in the event log that there was no certificate for mail.mydomain.com to be found. So, loaded with my new knowledge of certificates, I went to work.
I went in the EMC and created the cert req using the friendly name of mail.mydomain.com. This action created a req file on my desktop.
I then went into https://localhost/certsrv
and pasted the encrypted key into the web page and proceeded to create my cer.
I then went back to my EMC and completed the req using the cer file I now have.
As soon as I did that, my cert disappeared from my EMC and I can't find it nor can I confirm if it's installed and running now.
Seriously, what's going on?
