Setup:
- Machine A has Scheduling server and Storage server only (Runtime edition)
- Machine B has Test Studio and Execution Server only
- Execution server is configured to talk to Scheduling server on machine A

If you take a Fiddler trace on machine B you will discover that Remote Executor is attempting to ping a storage server on the local machine (machine B) at port 8492. It constantly fails with error 502, unable to connect.

While this is a benign error, it should not be trying to ping it in the first place.
