Thank you for reaching us out.
As of the shared details it seems that the MongoDB service cannot be started by the Windows service manager. I would recommend you review the MongoDB log file for further details - this could be found in C:\mongo\db
under the name mongo-server.log.
If you will need further assistance it will be useful to send us that log file.
The Telerik Storage service relies on that MongoDB service and it will not work unless that is started successfully. Once you are able to navigate to localhost:27017 in a browser instance (which ensures the Telerik Storage service is running) you will be able to run tests remotely.
I hope this information will be helpful for you. In case of further questions, please let me know. Thank you for your cooperation!
