[ubuntu-uk] Accessing Shared folders on a Windows 7 machine from Ubuntu 10.04

[Gordon Burgess-Parker]

I have removed the Homegroup , replaced it with a Workgroup and shared 
folders on the Windows Machine.
I have installed Samba and changed the Workgroup name on the Ubuntu 
machine to match that of the Windows 7 machine.
The Ubuntu machine sees the 7 machine, but all that happens when I try 
to access the shares is that the log-on screen keeps returning and I 
can't access the shares.
Any thoughts as to what I should be looking at?
