How to switch Windows 2003 server from file server to network applications model

we are running Oracle 11g 64 bit on a Windows 2003 64 bit server.

Below is taken from oracle docs.  It says to reset Windows server memory model from file server to a network applications model.

My question is, how is that done?

Thanks for any help.

Configure Windows Server to Be an Application Server

Windows memory manager divides up system memory into three different pools described in Table 7-1.

Table 7-1 Windows Server Memory Shares

Pool	Percent of Total Memory
Kernel and other system services	9%
File Cache	41%
Paged Memory	50%

Windows Server memory manager tries to balance each application's usage of memory by dynamically paging memory between physical RAM and a virtual memory paging file. If an application is particularly memory-intensive (like Oracle Database) or if a large number of applications are running concurrently, then combined memory requirements of the applications may exceed physical memory capacity.
