Ok, that makes sense. Couldn't read that from your first report so assumed
things. I've been able to set up a similar situation: drop a Samba server in
the network and share a folder, then mount over SMB. That all works as expected
and I have a local mount at /media/bktest.

Within winecfg I can map D: to any folder on the mount but it results in the
same issues (drive not available, error=76) when trying to use it in BK. So...
I've been able to reproduce the error. I'll now dig deeper into the system to
see where it's going wrong.
