Trying to give something back to the Community...
The HealthcareMDT2010 is now available for download which includes the x64 version of SMS Trace (many thanks for the heads up on this one from my good friend Johan Arwidmark in his post on this).
Details and link below:
Healthcare MDT 2010 is a customized version of The Microsoft Deployment Toolkit that allows IT administrators within a healthcare organization to create and maintain a customized Healthcare Desktop or Server build image in an automated and repeatable manner. Healthcare MDT 2010 helps healthcare organizations decrease the time required to develop a server or desktop build, and reduce errors associated with creating builds.
