TSM client - Windows 2003 server - SP2 x64 5.5.0.6

Started seeing these errors:

06/19/2008 11:02:58 ANS1009W An error occurred processing the operating
system include/exclude statements.
The error was detected while processing:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\BackupRestore\FilesNotToBackup\DRM.
RC = 13.

Went through the registry editing/key correction process as per IBM doc.

Now we get the errors:

06/20/2008 10:49:17 ANS1468E Backing up Automated System Recovery (ASR)
files failed.  No files will be backed up.

Did everything suggested. Deleted ASR stuff on TSM
server........Completely deleted the C:\adsm.sys directory

All to no avail. Manual and scheduled backups still fail.

User even tried complete un/reinstall of the TSM client.

Any other suggestions to fix this?
