Thanks for the post. It seems like your auth.config file is corrupt. You need to delete that file from C:\Program Files (x86)\Technitium\DNS Server\config\ folder and start the DNS server again. This will cause the file to be generated with default values and you will need to recreate users/groups that you may have had earlier.

Also, do upgrade the DNS server to latest version.

Technitium DNS Server v12 is now available which will give more specific error message when auth config file is corrupt.
