Shipping of CD 51031444 for Cluster components Windows Server 2003 64 bit

Hello,

we are planning an upgrade from our 4.7 x200 system to 64-bit platform on windows server 2003 with sql server 2005 in a cluster environment. The recommended CD for this purpose (CD 51031444) is no longer available in marketplace. Do you have any ideas where i can find the relevant components for such an installation? Is there an actual CD/DVD which contains these items.

Thanks ahead

Stefan
