I just did a clean install of Windows Server 2012 R2 Essentials on a Hyper-V box (Server 2012 R2 Standard with GUI) and went through the Essentials wizard just fine (checked the date and time, but they were already correct). When I tried to set up Anywhere Access and re-use a hostname on the remotewebaccess.com domain, it gives me this error:
"The certificate for your domain is not valid according to the server's date or time. This may be caused by the wrong date or time setting on your server. Please ensure that your server has the right date and time and try again."
I can't stress enough that the date and time is correct, and was correct when the initial domain configuration was run during the Essentials setup. It matches my Hyper-V host. Initially, I had Time Synchronization turned on via the VM settings, but I tried turning it off and re-running the Anywhere Access wizard, and it still fails.
What can I check, and how do I fix this? I didn't run into this problem the last time I installed Essentials 2012 R2. I didn't play around with any certificate settings either, although I did check the Effective Date for every certificate and they start on 11-27-2013 at ~2PM, which is when I did the setup.
Also, I tried setting up a new remotewebaccess.com hostname, and the same error comes up.
I'm going to try a re-install of the OS in another VM and see what happens. Will update if it happens again.
