Upgraded to QB's Pro 2009- still having same problem

US QuickBooks Pro for Windows : 2009

We are still having the problem with generating reports, they are taking way too long to produce. Not only does it take forever, when we try to cancel report by hitting the Esc. Nothing happens? We have a network of 4 users plus 1 server, I have searched up and down the forum, any suggestions?
Here is our systems operating info:

Server: Microsoft Windows Server 2003 for small business server Service pack 2
Intel(R) Xeon(TM) CPU 2.40Ghz
2.39Ghz, 1.00GB of RAM

Computer 1: Microsoft Windows XP Professional Version 2002 Service pack 3
Intel(R) Pentium(R) Dual CPU E2160 @ 1.80Ghz
1.80Ghz, 0.98GB of RAM
Physical address extension

Exactly how long is your forever?
        For what reports, with how many list items and periods?
        Do you get any error messages?
        Many divorces end forever marriages far faster.
        I well remember one QuickBooks add-ons forever that happily only took three years
Do you know about the first View choice?
        It lets experts limit extra open Windows and quickly switch between them.
        Extra windows are the quickest way to slow you down.
Do you know the Desktop Preference that does not save open windows when closing?
        This stops many reports from regenerating.
Do you know the Report Preference that only refreshes reports when you hit Refresh?
         Not setting that alone could kill you in a multi-user setup with many open reports.
Do you have 1g of main memory on workstations and 2g+ on the server?
          I gladly upgraded a small network to twice this.
Do you have automatic updates check for updates every time you start Windows or QuickBooks?
          Do you do this with all computers?
          There are only about 12 updates a year.
          You can share updates.
          One workstation can automatically tell others to update.
What is your file size?
Server and workstations free disk space at 20%+?
Did you temporarily turn off virus, spyware and firewalls?
Did you copy the QuickBooks file to a local wokstation?
       It can run reports single user.
Did you try the QuickBooks Network Diagnostic Tool at http://support.quickbooks.intuit.com/support/networking/nettool.aspx ?

Would you like to have any combination of QuickBooks reports automatically run at night, or on many day, night or weekend schedules, when most or all workstations are off? What if you can print or email any reports anywhere, or even get some or all in Excel?

Would that be worth $1,000? $500? $200?

Welcome to the world of QuickBooks add-ons, where you can have these automatic reports for only $100. There are thousands of such QuickBooks add-ons. They are the fastest and easiest low-cost way to solve many of your worst BUSINESS problems (not simply QuickBooks or accounting problems), especially if you feel you may need QuickBooks Enterprise or seem to be outgrowing it. QuickBooks, plus the right QuickBooks add-ons (in which I specialize) can easily handle companies with thousands of employees, while giving you capabilities that many big company people may dream about.
