how congested is your network? is the gigabit card on the server near
100% utilization, or also are your network switches near 100% bandwidth
utilization, or both? are you using roaming profiles? i'd try to
offload some of the network load by re-directing my documents to their
home directory so that roaming profiles doesn't have to copy that data
at login/logoff. if your switches are already congested, I don't think
a 2nd nic will help much. if you had some money you could buy more
switches. I like how the cisco switches handle VLANs well to break up
use unison for the mirroring of the folders, google for it. its like a
i can send you some old emails from the list i saved with various
helpful samba login scripting if you want me to forward you copies of them.
