I'm trying to retrieve some old archived data with dsmc from thatnode to 
thisnode, and I seem to have forgotten the strange magic involved in correctly 
specifying the paths.  So on thisnode,

dsmc> q filespace -fromnode=thatnode

shows me things like

\\thatnode\c$
\\thatnode\e$
\\thatnode\f$

but something like

dsmc> ret \\thatnode\c$\*.* -fromnode=thatnode

and various permutations just returns a message about nothing being archived by 
that path name.  What am I missing?
