Impossible to send Sentinel objects to production :
The lookup URL can't be resolved
error message is reported in the broadcast browser

1. Is your Sentinel server and Broadcast Agent are started or not? They have to be started.

2. Verify whether the patch/SP levels on Sentinel Server/Sentinel Enabler/Composer Server respect the readme instructions.

3. Whether the Sentinel RMI port defined in Sentinel parameters tab of XIP component is a valid port.

4. Do you have any network problem? Can you ping to the Sentinel server installed machine from Designer client installed machine?

5. If the sentinel server has multiple network adapters, the rmi-service will be bound to one interface. Check in the startup message, which ip address is used for the rmi service. By editing the RMIRegistry/NetworkAccess/hostname in trkserver.xml you can define to which ip-address the rmi service will be bound.
