Look for a config file named TrustedWSRPProducers.config in the folder C:\Program Files\Microsoft Office Server\12.0\Config.
This config file basically lists the information about WSRP Producers that can be hooked up to the SRPConsumerWebPart from a front-end. This file is expected to be in the above mentioned directory in all the web front ends.
Also the directory mentioned above should have a sample file TrustedWSRPProducers.xml.sample. This sample file should give you an idea about the format of the file and key elements of the file.
You can start by renaming the sample file to TrustedWSRPProducer.config (modify the URL elements to point to the WSRP server of your choice) and then configuring a WSRPConsumerWebPart to any portal page. Remember that if you are using a farm environment to make sure that the file is present in all web front ends of the farm in the specified path.
The reason for having a config file is purely for security (to avoid spoofing attacks etc). We only want farm administrators (who have access to the file system path mentioned above) to be able to govern which WSRP Producers are safe for connecting via web parts as opposed any site/page user .
