Opening a Windows Vista shared folder from Raring

[John Hupp]

I had no trouble in 12.10 Quantal opening a Windows XP share from the 
file manager, but in a fresh install of 13.04 Raring, I tried to open a 
share on a Windows Vista machine and depending on whether I tried to 
open Windows Network or entered smb://<machine-name>/<share-name> in the 
file manager address bar, I got one of these errors:

"The specified location is not mounted"

"Failed to mount Windows share: Connection timed out"

This is a known issue with a solution?
