Error 0x800706BA = "The RPC server is unavailable"
Check firewall settings on the server that you're trying to install the DP role on.
Looking forward, it's making a connection to WMI remotely, so whatever account you're using to install the role (Site Server account or user account) will need to be in local admins as well.

Hi,
The account used to install the DP has local admin access. What should I check in the Firewall settings?

OK, so when you're getting a 0x800706BA (RPC Server is unavailable), that means you're making an RPC call from point A (site server in your case) to point B (DP to be) and it's not getting a reply. In many cases, this is a firewall setting that's blocking

• TCP port 135 (RPC Endpoint Mapper) inbound on the point B
• The Dynamic RPC ports either outbound on point B or inbound on point A

What's the status of the RPC Endpoint Mapper service?
