network problem

I’ve installed V6 several times but have to uninstall it again because of network problems.
When I go to copy a file from one computer to another over the network it takes forever to
“discover” the file first on computer one and then after a ridiculous time it takes forever
again to send it across the network. No such problem with V5.
Does anyone know what’s going on here, I’m sure it’s just a tweak somewhere but so far I
can’t work it out.

Thanks for your help, looks like I stay with V5 or look elsewhere
