I have an issue with all computers in AD:

I'm getting this error after creating VBScriptEngine with debugging flag: either a required impersonation level was not provided, or the provided impersonation level is invalid. 

(Exception from HRESULT: 0x80070542)

The problem is around this line:

processDebugManager.AddApplication(debugApplication, out debugApplicationCookie))

where processDebugManager is COM: 

{78A51822-51F4-11D0-8F20-00805F2CD064} [IProcessDebugManager]

Impersonation is enabled in the local politics.

Any ideas which restriction could it be?

    Recommend better justifying the C++ tag. Perhaps C++-cli is more fitting? – user4581301 Aug 10 '18 at 17:45
  • Any error starting with 0x8 is a null pointer. It could be due to access privileges, or trying to access un-managed memory from the c# application. It looks like it may be a cookie issue and the user don't have the cookie loaded in their cookie folder. May be an expired cookie. I would try to clear all cookies from the IE and try again. – jdweng Aug 10 '18 at 18:10

Forgot to add a solution. This error 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
  2. Open system services window:

    click "Start" -> then type "services" and select it (or find this console via "Control Panel" -> "Administrative Tools"):

  3. Click right mouse click on " Machine Debug Manager" and open "Properties" Stop the service (click the stop button) and disable it (change the status Type)

  4. Reregister system DCOM MDM Open cmd as an Administrator:

    click "Start" -> type "cmd" -> right mouse click -> "Run As Administrator" Register the server: WIN 32 (x86): type the command: mdm.exe /regserver

    WIN 64 (x64): type the following (we have to change the directory to SysWOW64):

    cd ..\SysWOW64 mdm.exe /regserver

Restart the computer.

If you get access issues, please check DCOM permissions

(Run -> "dcomcnfg" -> Find "Machine Debug Manager") Go to: "Component Services" -> "Computers" -> "My Computer" -> "DCOM Config" -> "Machine Debug Manager" Right mouse click -> select "Properties"

Open the "Security" tab and recheck permissions. Try to add everyone (or someone special) to understand that it's a permission issue.
