have you got available memory on the host? Are you overcommitted?

In vCenter, select the host and then select the Performance tab.  Do you see any memory ballooning activity? Are there any resource limits on this VM? What sort of applications are running within the VM?

I would check these articles

1. Check and correct CPU utilization: CPU Performance Analysis and Monitoring

2. Identify memory bottlenecks and remove: Memory Performance Analysis and Monitoring

What functions does the Windows 2003 server perform, how much memory has been allocated to the VM, how much memory is in the host?

Commented:
it is a terminal server and host has 40 GB of ram and guest has 12 gb of ram.

Commented:
As your host is running at 20% that would mean 8 GB used, so your guest isn't using all of it's available memory.

Another question: what version of Windows Server 2003 are you running (Standard, Enterprise, 32/64 bit) ?
Only if you are running 64bit Standard or Enterprise you will be able to use the memory above 4GB.
You do NOT want to use PAE on a terminal server!
