  Hello!

  If you get the following error regarding the impersonation – it could be the problem with wrong registered Machine Debug Manager:

  [center]

  It means that we have installed the mdm (Machine Debug Manager) from VS2002 (which is not used anymore). To fix it we should perform the following steps:

  1. Disable MDM service
     [li]Open system services window: click “Start” -> then type “services” and select it (or find this console via “Control Panel” -> “Administrative Tools”):
     [center]
     
  2. Click right mouse click on ” Machine Debug Manager” and open “Properties”
  3. Stop the service (click the stop button) and disable it (change the status Type)

     [center]
     

  [/li]

  4. Reregister system DCOM MDM
     [li]Open cmd as an Administrator: click “Start” -> type “cmd” -> right mouse click -> “Run As Administrator”
  5. Register the server:
     [ul]
     [li]WIN 32 (x86): type the command:
     [ul]
     [li]mdm.exe /regserver
     [center]
     

  [/li]

  6. WIN 64 (x64): type the following (we have to change the directory to SysWOW64):
     [li]cd ..SysWOW64
  7. mdm.exe /regserver
     [center]
     

  [/li]
  [/ul]

  [/li]

  8. Restart the computer.

  [/ul]

  [/li]

  9. Work with ZAPTEST. If you get access issues, please check DCOM permissions (Run -> “dcomcnfg” -> Find “Machine Debug Manager”)
     [li]Go to: “Component Services” -> “Computers” -> “My Computer” -> “DCOM Config” -> “Machine Debug Manager”
  10. Right mouse click -> select “Properties”

      [center]
      

  11. Open “Security” tab and recheck permissions. Try to add everyone to understand that it’s a permission issue.

  [/li]

  Thank you,
  ZAPTEST Team
