This configuration string is the path to the directory containing the data you want to transfer using a multicast transmission. To resolve this issue, create the namespace again by using the /ConfigString command-line option to specify the correct file path to the directory that contains the content.
Note:
To perform this procedure, you must either be a member of the localAdministrators group or have been delegated the appropriate authority.
To create a new namespace:
1.Open theCommand Prompt window.
2.At the command prompt, runWDSUTIL /New-Namespace [/Server:] /FriendlyName: /Namespace: /ContentProvider: [/ConfigString:] /NamespaceType:{AutoCast | ScheduledCast} [/Time:] [/Clients:].
Verify :
To verify that the registration occurred:
1.Open the Command Prompt window.

3.Make sure that the output contains the namespace you registered.
