In reply to David.

HI David,
It is not a deployment server. The deploymentregistry files comes from a sas server or pc where sas is installed and running.

You then can take the deploymentregistry file to another machine if needed - on the system where you plan to run the SASHFADD tool to generate your SAS Hot Fix Analysis Report.

I hope that makes sense. Please let me know if you still have questions.
Have a great day,
Sandy
