Have you looked in Task Manager?  Open Task Manager and look at the memory area. It should show you how much memory is used out of how much.

Your system says it has 4Gb of memory. It is a 32-bit machine (likely) and so will only likely use 3Gb unless you turn on (and can turn on) PAE mode on the server to allow addressing extra memory.

Systems do not always use all the memory and so perhaps that is the case here.

It probably just is not a fast server in today's terms and if running lots of things, SQL is likely to be slow. I do not know if you can force SQL to use more memory.

Here are a couple of Microsoft Support sites for PAE.

http://support.microsoft.com/kb/283037

and

http://msdn.microsoft.com/en-ca/windows/hardware/gg487503.aspx

Look through those. I do not know if it is a given that PAE works on any server. So look through both articles and see if they apply

Hello Dear,

To enable PAE on a 32 bit Window 2003 OS click on run in the start menu. Type sysdm.cpl in the text box and click enter. Next click on the advanced tab and choose settings from the performance heading. Then click on the data execution prevention tab and go to the bottom of the box to see if it PAE is enable or not. If it is not, go back to run in the start menu and type notepad c:\boot.ini and click enter. Find the /noexecute switch and enter a space and /pae at the end of the /noexecute command. Your next step is to save and then restart your computer to activate the changes.
