samba

[nowayout]

hello all,

I have fedora core3. I configured samba to share files from windows.
When i go to windows network places and trying to connect to fedora i
get an error

""\\Localhost is not accesible. You might not have permission to use
this network resource and blah blah.. at the end say you are not
connected because a duplicate name exists in the network. Go to System
in Control Panel to change the computer name and try again"

Could somebody help?
