Recently I installed an Add'l DC on the company network. The original DC is a Windows 2008 SBS and the second DC is a Windows 2008 R2. The SBS server is also the Exchange server and the R2 DC is just a "backup." All was going well until I had to reboot the SBS server last night for a software update.
On boot up, now i get errors about the certificate authority and dns. Can anyone help?
