PPM is a .NET-based application, so there are Microsoft Distributed Transaction Coordinator (MSDTC) security settings that are critical to the security of the application.
You need to ensure that particular settings are selected. If you are using Windows 2008, these settings are located on the Local DTC dialog box Security tab:
- The Network DTC Access option
- The Allow Inbound and Allow Outbound options
- The No Authentication Required option
Ensure that these settings are set correctly on all servers, including the database server.
Refer to the Installation and Upgrade Guide for Primavera Portfolio Management for more information about MSDTC settings for PPM and for details about how to set them.
