I got SBS 2011 Server with installed domain and Exchange 2010 installed, named "SBS".
I have 2nd DC installed on 2012 R2 Standard in the same domain, named "server-04". It is completely updated.
Both DCs work OK, replicate to each other with no issues.
I am trying to install Exchange 2013 SP1 as a second Exchange server (in order later to get rid of the first one - 2010) on a 2nd DC "server-04".
To install Exchange, I use an admin account that got membership in: Domain Admins, Enterprise Admins, Schema Admins, Organizational Management and Exchange Servers. However, Prerequisite Analysis stops the installation with an issue. I tried to restart the server, but the same issue came up again. The issue is:
