How can I monitor network activity for potential bottleneck?

Server:  Windows 2008-R2 Server also running Exchange Server 2010.  12 GB ram, lots of free disk space.  Billing software (Tabs3) also installed on the Server.

My computer:  Windows XP Professional.  A shortcut (Tabs3) is on my desktop that points to the executable file on the Server.

When I click the executable, my cash receipts report is generated in under 2 minutes.  Yet at other times, when I run the same report, it takes 1 hour to complete.

As a test this morning, I
(1) disabled anti-virus on the server,
(2) disabled anti-virus on my computer,
(3) disabled exchange server 2010,
(3) disabled internet access for everyone (by powering off the cable/modem)
the same report still takes 1 hour to complete.

Now, with everything enabled again, the same reports takes 1 hour to complete.
On the Server, I looked at Computer Management, Performance, Open Resource Monitor, I get the following results:

3% Network Utilization
1% Disk activity
4% CPU usage

Where do I begin to determine what is causing the slowness and/or bottleneck?

Thanks for your help!

Does Tabs3 use SQL Server (or any other database located on the server)?

it is most likely the database that is the bottleneck. Other people are using the database, the database is an old architecture.

We purchased the multi-user version of the software.   We did not purchase the Client/Server version because it was more expensive.
