Help please with Windows Server 2003 R2

Hi
It appears as though someone has deleted the I386 File on our server Machine.
We have recently moved and it appears it happened in the move, combined with the Fact that the Finance Lady that keeps all the CDs has lost the Windows CD.
Is there anywhere on the Web that I can download the contents of that Folder?
We need it to start the Webserver and the IIS
Thanks
