To resolve this issue please do the following:
  1. Open task manager.
  2. Find and end the MCPSHostServer.exe process if it exists.
  3. Restart the NetIQ Client Resource monitor and Client Communication Manager.
  4. Run Discovery_NT against the machine.
  5. Create a new job on the affected agent, using the Powershell_RunCommand Knowledge Script.
  6. Use the following command in the KS parameters to test if powershell is working properly via the KS.
If this works correctly, then re-attempt the discovery for XenApp. If discovery is still unsuccessful please contact NetIQ Technical Support.
