Solution

This issue occurs because the Service account does not have sufficient permissions to create a WCF end-point on the specified port (by default this is 59990).

To provide the service account with the required permissions enter the following into command-prompt.

netsh.exe http add urlacl url=http://+:DESIRED_PORT/ user=DESIRED_SERVICE_ACCOUNT        

Other solutions include:

  1. Changing the service account to an account that has the required permissions - specifically if the original service account should not be able to host services on specific ports.
  2. Changing the port to one that the original service account supports - specifically if the service account cannot/should not be changed.
