[Samba] rh8.0 and xp home

[Dragos]

I have two networked pcs.
pc 1- RH8.0 which came with Samba-backend 1.0.8 and Samba 2.2.5
pc 2- XP Home

I am able to access the shared folders from pc2 on pc1.
However from pc2 I can not even see the ressources of pc1.
In My Network Places/Entire Network/Microsoft Windows Network/"My 
Workgroup" I can see "pc1" but when I click on it I get an error 
message: \\"pc1" is not accessible. You might not have permission to use 
this network resource. The network path was not found.

I have not been able to find any doc about samba and xp home so any help 
is appreciated.

Thank you
Dragos
