How do I configure MSDTC properly for AD software?
On all servers involved in your Summation/eDiscovery setup, enable the following Security settings in your Local DTC Properties
Click Start → Administrative Tools → Component Services → Computers → My Computer → Distributed Transaction Coordinator → Local DTC
(Win7 : Control Panel\System and Security\Administrative Tools)
Several issues will arise (including a failure when creating cases) if MSDTC has not been configured properly.
