I won’t copy-paste whole post, but here is the bottom line: It’s a little surprising that the SID duplication issue has gone unquestioned for so long, but everyone has assumed that someone else knew exactly why it was a problem. To my chagrin, NewSID has never really done anything useful and there’s no reason to miss it now that it’s retired. Microsoft’s official policy on SID duplication will also now change and look for Sysprep to be updated in the future to skip SID generation. So, there is no need to change SIDs anymore. Good news.

When the server image was created, was the server joined to an AD domain and a Citrix farm as part of the SME verification testing? Was the server unjoined from the AD domain and/or Citrix farm prior to executing the XenApp prep utility? Thanks! Thank you, great step-by-step instructions in this blog post.
