Small Home Network PC Visabilty Prob

[#1]

Got a small home Vista network,
2 pc's (A: Cat5 Desktop (Vista Premium), B:Wireless Laptop (Vista Home))
Thompson Router
Vista Extender
PC A: can see all devices, PC B and its public folders
PC B: can see all devices but not PC A?
Both run Norton 360's firewall
Both can access Internet through router
ANy ideas why A can see B but B cannot see A:?

Thanks in anticipation

Maybe Vista Premium security settings?  Are both machines in the same Workgroup (or whatever the Vista equivalent is)?
If you want to waste a day, try getting a Vista and XP machine to see each other!

Have you got exactly the same user names and passwords set up on both machines?

[#4]

No different usernames and passwords

have you tried disabling Norton

Is Vista the same as XP in that you have to make sure that the LAN connection properties has File and Printer Sharing for Microsoft Networks enabled on both PCs. Also on XP the Professional defaults to higher security than the Home edition so I guess that could be similar.
