We recently replaced the server and OS to NW6 with ZfD4 & NFAP in a
middle school. Since then, some of the Macs are experiencing slow data

transfers when transferring either from a mac to the server, or from
mac
to mac. No network equipment was altered or replaced in this upgrade.

What could be causing the slow performance?? Incompatible Mac OS's
with
NW6 & NFAP ??? HELP!!!!
