Net performance

I’m a Unix Admin as all of you who are reading this probably are, but if any of you work in a heterogeneous environment that uses W2K desktops, I have a 2500 point question under Windows 2000 that is titled “Net Performance in heterogeneous env.”. It deals with problems I think I’m seeing when W2K clients try to talk to non-W2K servers for FTP/folder shares/etc. I’d really love to find a fix to this scenario. Please check out my question under Windows 2000 and respond there, not here. I appreciate any help/validation you can provide.
