FSRM for Windows Server 2003 Standard SP2

Hi,

We have a File server with Windows Server 2003 Standard Edition and Service Pack 2 applied to it.

We would want to use File Server Resource Manager component which through research we understood comes with R2 version.

Is there a patch available from Microsoft to install FSRM on our server ?

Is there a workaround to have that feature available ?

Thank you for your suggestions.

Best Regards,
Aravind.
