I know going on with this is going to seem like I have to be write but I think 
I've done a poor job of pointing out what I disagree with you on. So here goes 
one last time.
   
  She said the following:
   
  If I DON"T map a drive letter, but I add that same drive to my dsm.opt file 
this way:
DOMAIN ALL-LOCAL \\host\d$ Assuming I have the right permissions, the scheduler 
will back up this drive just fine. But when I open the GUI client and do edit 
-> preferences -> backup, it isn't in the domain list, and I can't select it 
from the GUI.
   
  Is this WAD? I found in the doc where the unc name is allowed in dsm.opt, but 
can't find an explanation of the difference in the scheduler and GUI behavior?
   
  To which you said:
  Hi Wanda, I would call this a bug.

   
  I believe:
  No it is not a bug. Putting a UNC path in the domain statement will not make 
it show up in the GUI under backup. It never had.  A UNC path is not a mapped 
drive.  Further she gave another example about when she put a mapped drive in 
the dsm.opt's domain statement it showed up in the GUI. To that I say it wasn't 
the fact that she put a mapped drive letter in the dsm.opt that caused it to 
show up under Network but rather it was simply the fact that the drive was 
mapped. You could have just had "ALL-LOCAL" in the domain statement and you 
would still see the mapped drive in the GUI.
   
  The thing I want to make sure everyone is clear on is that the domain 
statement is not what the GUI uses to build its list of what you can select to 
backup.  The GUI simply lists all local drives under local and mapped under 
Network. And of course mount points and other things were appropriate. But UNC 
paths never show up because they are remote things not locally mounted or 
mapped.  Putting them in the dsm.opt's domain statement will in no way add them 
to what you see in the GUI for backup.
   
  Now all this can be confusing because once you do backup a UNC it does show 
up under restore but that is only because once backed up it is now a new 
filespace that can be restored.

PS.
  I'm sure you are correct on all your points. Sorry for my poor manor in 
conveying what I was asking. I hope this was better.

She was referring to the *preferences editor*, specifically the BACKUP tab
where the domain list is pre-filled with available file systems that you
an add to the list. She was saying that TSM otherwise treats the share as
a valid domain object, so why doesn't it show up as a selectable item from
the Backup tab's list of available file system objects.

And I agreed, saying that the absence of this object seemed like a bug.

And by extension, I would also expect to see such a share show up in the
Network part of the GUI's backup window, but yes, *that* specifically has
nothing at all to do with domain.

Andy
