Re: can get 'net use' to give remote share a drive letter when logged in directly but not from ssh session

If you're running 1.7.X where X <= 1, this might be fixed by upgrading.
Those versions had a bug where the user's registry was not properly
initialized via ssh.  To see if this is your issue, you should be able
to run the "reg query hku" and see if you see your SID listed.  Another
symptom of this problem is that ssh will work if you are simultaneously
logged in via remote desktop.  You might want to check those if you want
to check those to see if the upgrade might help.  Frankly I'm not precisely
sure your symptoms are related that problem but they are in the general
area of those issue, so it's worth a look.

This works if I make a Remote Desktop Connection to

In fact, the local device name is not in use. Same result no matter

Bottom line: I can use 'net use' to connect to a remote resource

I'm not sure if this is relevant, but as a
