It depends on the RAID controller used. In Servers you often have hot swappable disks, and there you would normally just remove the bad disk and replace it with the new one while the system is up and running. And then check the array configuration utility you have installed within windows, you may have to initiate the rebuild there if it doesn't do that automatically. But mainly you have to find out which smartarray controller you got with your server, and then check it's manual about it's capabilities.

It will either have a P400 or E200 in it, as rindi says just pop the failed disk out and put the new one in, rebuild is automatic as long as you do it live.

If 2 disks in a RAID 5 array have actually failed, you have lost the data and there is nothing you can shift to another server. You will have to replace the 2 disks and rebuild the array and then, if the OS was on that array, re-install the OS or restore it from a backup. If the OS sits on another array, restore the data from your backup.

Maybe you should think of a new RAID setup since you will have to do it new anyway. If your controller supports RAID 6 go for that, as with RAID 6 two disks can fail while the array is still functional. For RAID 6 you just need an additional disk compared to RAID 5. You could also add a further disk as a hot-spare. That would start the re-sync automatically as soon as a disk fails, and so a degraded array will be degraded for less time, as you don't have to wait for someone to replace the bad disk until the procedure can start. Of course your server needs enough free disk bays to take the additional HD's.
