Network Monitoring Software

Hello and Happy New Year.

I support a network with some pretty dated equipment like a Cisco 2900XL
switch (unmanaged). That is the newest piece of LAN/WAN hardware. <sigh>

I am looking for some recommendations on [free] software that I can use
to monitor my office-to-office subnet traffic and bandwidth utilization
as there are time of the day when user's cannot get to important files
from the [single] Windows 2003 Server Standard SP2 we have in the
domain. Any graphical statistics generation capabilities as opposed to
filling an Excel spreadsheet would be a plus.

Thanks in advance for any suggestions and tips.

I would recommend using MRTG to graph utilization of switches/routers,
Perfmon on your servers and Wireshark to see what exactly is going on.

Since you mentioned a 2900 in particular, it'd be worth looking into
SPAN (or port monitoring) capabilities that might be available and using
that with Wireshark to see what is going through particular interfaces.
