network browsing and sharing

[Haldor Riddering]

Hi,
how do I share folders on my laptop so windows users can access the 
files over the network?
also is there a network browser for kde? something that will browse 
windows shares automagically.
I can do it smb://ip.address but don't always know the ip of the 
computers on the network where I work and was hoping for something to 
connect to the workgroup and tell me whats available.

thanks heaps
