I think it's a permissions issue. Still, in no particular order, some things to check:
Are both computers connected to some router which is connected to the Sky box?
Are they both XP-home?
Are both computers members of the Ahome workgroup (MyComputer > Properties)?
Are guest accounts enabled on both or if XP-Pro, are the users setup correctly?
Are the folders to share put in the Shared area, or if XP-pro, are the permissions to share given to the users?
Are the software firewalls blocking broadcasts to the router? (probably not, since you can read off the directory structure, so this should be ok)
The office PC (Named 'Auto') does NOT have Microsoft terminal Services or Web Client Network. I don't know why.
I doubt they're needed. You do need the Worstation service to run, and likely NetBios over TCP/IP (Network > Properties ... TCP/IP and drill down till you see something to click for NetBios)
If the office PC is part of a domain, XP-home doesn't seem t work with it too well. Both need to be members of a workgroup, I believe.
