I have 2 SQL Servers in a Domain. Windows Firewall is disabled on both servers and there is no hardware firewall. Both servers are in the same subnet.

One server, called Controller is configured as a Distributed Replay Controller. The other sever, called Client is configured as a Distributed Replay Client.

The Distributed Replay Controller service is started, but when I try to start the Distributed Replay Client service, I get the following error in the Client Log:

[0xC8100005 (6)] Failed to connect controller with error code 0x800706BA.

In the Windows System log, I see the following error:

DCOM was unable to communicate with the computer controller using any of the configured protocols; requested by PID      830 (C:\Program Files (x86)\Microsoft SQL Server\120\Tools\DReplayClient\DReplayClient.exe).

The same account is running both services and this is actually a Domain Admin (Yes I know that's bad practise, but its a sandbox environment), and I have checked that the account specifically has the following DCOM permissions set on the Controller:

Local Launch Local Activation Remote Launch Remote Activation Local Access Remote Access and Full Control for configuration

Both servers running Windows Server 2012 Datacentre and SQL 2014 Enterprise

I have even tried giving the Domain's Eveyone group these permissions.

I have even rebuilt the Controller.

The servers can ping each other via both IP Address and Name

You need to configure DCOM permissions as DCOM is used for the RPC communications between controller and clients as well as the controller and administration tool. I think this link might help you (under the heading DCOM permissions). msdn

I won't repeat all the info on here since its on the msdn page but following all the steps on there allowed me to get distributed replay working.
