How do I configure Summation or eDiscovery to use Distributed Processing? 



  • A domain-level service account with local administrator permissions to all involved machines and full access to case, evidence, and export shares.
  • Open the following incoming ports on the servers running their respective components:



    Microsoft SQL Server

    1433 (or custom port)

    Distributed Processing Manager


    Distributed Processing Engine


    All machines

    135 (DTC), 1024-65535 (DCOM)


  1. Install both the Distributed Processing Manager and Distributed Processing Engine on the machine running the Work Manager component responsible for processing and export jobs.
    1. Make sure to check "Install as a Distributed Processing Engine" when installing the Processing Engine.
  2. Install the Distributed Processing Engine on any desired additional machines.
    1. Make sure to check "Install as a Distributed Processing Engine" when installing the Processing Engine.
  3. Open the Distributed Processing Manager Configuration, typically located at "[drive]:\Program Files\AccessData\Distributed Processing Manager\[version]\ProcessingManagerConfig.exe", as Administrator.
  4. For each of the machines running the Distributed Processing Engine, do the following:
    1. In the Computer name/IP field, enter the name/IP of the machine.
    2. Click Add.
  5. After adding all desired processing machines, click Save and Close.



  • Always use the same service account credentials for all components.
  • When installing the other Summation/eDiscovery components, when prompted for the "Processing Manager", make sure to specify the name of the machine that will house both the Work Manager and Distributed Processing Manager components.
  • While there must be a Distributed Processing Engine installed on the Work Manager machine for certain jobs, that machine doesn't necessarily need to be used for processing.  You can leave this machine out at step 4 if you do not wish it to be used for processing jobs.
