I do a lot of server-based development with CRM and as a result, I am constantly turning on ( and off ) CRM diagnostic tracing to see what is happening behind the scenes.

A few months ago, I wrote ( and later rewrote ) a utility that would make the registry changes for me.  This speeds up the process and I don't have to worry about introducing an invalid setting into the tracing engine.

CRM Tracer will work with both the CRM Server and CRM Client.

CRM Tracer can be found in the Premium Content section on my company web site.  Registration is required but the utility is free.
