Hi everyone,
After doing a few searches and not finding an answer to this I figured I'd see 
if anyone else has encountered this.

Running Windows 5.1.7client (the last supported client for NT) on NT 4 (sp6 I 
think).

Two drives, C: and D:

During a scheduled incremental, the C: drive gets backed up, system objects get 
backed up, but D: drive doesn't get touched.

No error messages, nuttin.  It's as if the drive isn't there.

There's no Domain line in the dsm.opt file, no excludes.

I can go into the GUI and see the drive, and manually backup the drive.

Same client on other similarly configured NT systems at same site seem to work 
just fine.

any thoughts?

Paul
