I've got an interesting one...
My users have always typed in 'mail' to get to their mail. There was an internal DNS A record that resolved that to the IP of the mail server.
I'm putting in an Exchange server to replace that. In order for people to get their mail, I try putting in an A record that does the same thing as the previous one. When I try to get to OWA, it tells me that the certificate on the server is not trusted. I only have the names:
so when the browser sees that this cert is trying to cover https://mail/owa it says the cert's not trusted.
What amy I supposed to do about that?
