Network slow in one direction

[Ken & Joy Carr]

We have a network with a Linux (FC2) server and several Windows (XP and
Win2K) workstations. Samba on the server provides shared folders for the
windows machines.

Opening files that are in a Linux-shared folder from a windows machine
happens very quickly. However, saving files from the windows machines to a
shared folder takes an excessively long time. For example, opening an 8 MB
file (in a server shared folder) using Power Point takes 1-2 seconds while
saving the same file takes over 5 minutes.

The problem is present from any of the windows machines and happens with any
of the shared folders. Different applications, and copying files using
windows explorer exhibit the same problem. 

Help, please.
