Dashboard & RWW not working in Server 2012 Essentials and constant eventID 36871 SChannel errors

Hi People,

Looking for help on a 2012 Essentials server that dashboard shows no users, computers, etc, RWW wont let clients authenticate and log in - says wrong password, and gives constant errors in the event log of 36871 "A fatal error occurred while creating an SSL client credential. The internal error state is 10013." and "A fatal error occurred while creating an SSL server credential. The internal error state is 10013.", 6 or more every second.

Quick run down of what happened to cause this:

Enabled RWW for users and installed a proper SSL certificate - all working fine for a week.

Disabed SSL 3 and TLS 1 for PCI compliance by adding the relevant keys in the registry (same as ISSCrypto does) - restarted and no longer able to log into RWW. Checked event viewer and getting 5 or 6 36871 errors every second.

Removed registry keys - rebooted and same error.

I believe it could well be a certificate issue.

I have tried https://support.microsoft.com/en-us/kb/2795825 but that hasnt helped and I have removed the installed Comodo certificate.

I have taken a VM of the machine so I can play around on that without killing a live system.

Any help would greatly be appreciated as I am a little stuck!

I would start by running the Best Practice Analyzer:

In the Dashboard, click the Devices tab.
In the Server Tasks pane, click Best Practices Analyzer.
Review each BPA message, and follow the instructions to resolve issues if necessary.

Post the problems it displays.

Check to see if AD Services are started.  In fact check all autostart services.

Do you have a backup of the server?
