Windows Server

I have an issue with a relatively straightforward client-server arrangement.
We have one server (configured as a DC, Exchange 2003 Server, and as the
principle file server).

There are approximately 30 to 40 workstations (all running XP Professional),
so th along on the infrastructure (100 Mbps switched) is relatively light.

All clients connect to a number of mapped drives on the server, which are
used for departmental and user file sharing. The problem appears to be a
very slow transfer between the client and the server (and vice-versa) to
these mapped locations. With even a small transfer of few megabytes taking
minutes to complete, whereas transfers between the workstations are much
quicker and take but a few seconds for the same size files.

Locally the server runs perfectly (with plenty of Processing, RAM and HDD
capacity), as does its network interface (which is connected at 1 Gbps).

I have read that disabling the SMB signing and changing the TCP ACK
frequency can help, but i have not noticed any improvement after making the
suggested changes.

I really don’t know where to start resolving this problem, and so hope you
can point me in the right direction.

Many thanks in anticipation of your most welcome assistance.
