It can be a number of factors...
Let's start with the server, then move to the LAN:
1) Are the hard drive partitions below 80% full?
2) Are the NTFS partitions defragmented? If not, download Diskeeper at:
<http://www.diskeeper.com>. One critical area to watch is the critical
Master File Table (MFT) area... You want that to be clean;
3) Shut down traverse checking by adding the REG_DWORD:
NtfsDisableLsatAccessUpdate value=1 to:
HKLM\System\CurrentControlSet\Control\FileSystem
4) How many Macs do you have in your LAN? Is your packet traffic so high
that the LAN is flooded with collisions? Try adding in a second or even
third NIC and split your LAN into half, or even thirds to cut down on
packet collisions.
I hope this helps!
