Multiple copies of shared comps in finder?

My wife and i just upgraded to leopard. I wanted a file off her desktop so went to finder and check under the shared location to access her computer. Her ibook g4 showed up with the correct name under the shared section. Although a duplicate of it shows up also. The thing is the duplicate has the same name instead of the ibook icon this one has the old windows looking computer icon? I can connect to the one with the correct ibook on but can't connect to the one with the weird windows looking icon. It can't delete it? why is it there? what's with the duplicate? anybody know?
