admin server connection issue

[step wright]

I have been uploading files remotely to my filemaker server using the admin console. However, it eventually crashed out. On reopening i get:

Admin Server Connection Error:

The admin server cannot establish a connection to the admin server

I have also tried opening the console from the filemaker server with the same result.

This has happened in the past. I have had to restart the entire server to get it working again. All web services are working, and clients can access the files. I have also installed all server updates.

Is there a service or something i can restart without having to bring down the entire server?

Thank you for your time
