The 4.1.2 Windows client includes an exclude system32\config statement that 
prevents the registry backups from being sent to the server.  TSM 4.1.2 now 
stores the registry files in a system32\config subdirectory of adsm.sys; all of 
the hkey_local_machine files are excluded from the backup.  Current clients 
that are upgraded would continue to use their existing settings and thereby 
lose their registry backups in the process.  I've added a include 
*:\adsm.sys\...\* to the bottom of my dsm.opt file.
