In FTK Core or Enterprise, when adding evidence to a case, you get the following error:

An unexpected error occurred adding evidence. Exception: CanAccessStateDirectory: There was no endpoint listening at net.tcp://servername:34097/ProcessingManager that could not accept the message. This is often caused by an incorrect address or SOAP action.


This error occurs when you installed FTK Core/Enterprise on your application server, then your server’s computer name was renamed or changed afterwards. 

  • To verify this, go to the path and open the ftk.exe.config file: C:\Program Files\AccessData\Forensic Tools\7.6\bin
  • Look for the entry called net.tcp://servername:34097
  • You may see entries of the server's previous name and as a result, FTK is still associated to this name



Due to the numerous XML and config files that contain the server's computer name, FTK will have to be uninstalled, and re-installed.


  1. From Control Panel>Programs and Features, uninstall AccessData Forensic Tools 7.6
  2. Go to Program Files\AccessData\Forensic Tools\7.6\bin and delete the contents of the bin folder (if using FTK Central, please make a backup of the file called ADG.WeblabSelfHost,exe.config)
  3. Restart your application server
  4. Install AccessData Forensic Tools
  5. Open FTK or FTK Examiner and verify you can add and process evidence in a case
