My memory is a little hazy, but from what I recall, I noticed the SMB
problem first in NetWorker 6.1.1. I successfully got an RFE implemented to
pull it out of 6.1.2, but it got put back into 6.1.3. Despite my arguments,
it was decided that SMB wasn't NFS and therefore wasn't in the same category
:(

I noticed Maarten still experiences it in 7.3.x; that doesn't surprise me at
all.

Cheers,

Preston.
