What is the amount of time that passes between when you first obtain the SID
and the time you obtain the SID and determine that it has changed?

Are you doing your first installation of software on a hard drive that is
later used to image workstations [e.g. SysPrep gets executed *after* your
software installation is done]?

There's only a few things that should change the system SID for a
workstation or member server. Running SysPrep and booting the system will
generate a new SID for the system. Likewise, running the NewSID.exe utility
will do the same thing. This SID is what is returned as the account domain
SID regardless of whether or not the workstation or member server belongs to
a domain or a workgroup. Only the primary domain SID varies depending on
domain or workgroup membership, and is NULL for a workgroup.
