changing hard drives on win adv. server

Hi all
Is there a way that i can replace my present hard drive on the server (win 2000 advanced server) with the minimum down time, and so that i do not have to configure the server again? I am fast running out of space on the c:\int.pub as i have a fast growing database.
History
1) I have an additional hard drive scsi as “d” where the complete pc is backed up.
2) My present hdd is divided into three partitions.
3) The server is host to an intranet page, on which i am running the database on. (SQL)

any suggestions??????
