This is the 64-bit driver for Server 2003x64 for the PERC H700 RAID controller: www.dell.com/.../DriverDetails You will need to make sure your 2003 media has SP2.  If not, you can use nLiteOS.com to integrate the Service Pack (and the RAID driver if you want). Remember, even with the correct driver, NO drives will be seen if you haven't first configured RAID in the CTRL-R utility.
