Robert:
The error code that you are seeing indicates that Backup Exec cannot commuincate with the remote agent. You asked earlier why it would need to communicate with itself in such a manner.
In 11d all the moving of the data for backups and restores is done through the Remote Agent Service, even local backups. Please verify that this service is running as the "Local System Account" This can be done by going to the services applet, and selecting the "Backup Exec Remote Agent" Look on the Logon tab and verify that the service is running as the "Local System Account"
Also your initial post indicated that either there was a server throwing this error that you were not trying to protect, or that this server was complaining about a URL being used.
Go to your selection list for this backup job. Under the selections, select the "View Selection Details" tab. this will give you the selections in text. Please verify the path and URL to the machines you want to protect with this job, and remove any extraneous selections.
