Once done with the unzipping you should see .NET client driver. I am not very sure about the configuration as I do this in java. For configuration in java, I add java client driver and selenium server in library there may be same procedure for .Net framework. This is only I can share with you.
I have only gotten Selenium RC to work with the Molybdenum add on. You have to use Firefox 3.0 (You can find it at: http://www.oldapps.com/firefox.php) to get the Selenium RC plugin to work with molybdenum.
After loading the two add ons and your script you just go to Molybdenum->Run->Selenium RC and point it to localhost or an IP address.
Anyone have a different way to run Selenium RC? -- I would love to hear it, as this is the only way I have found success.
