ahh that program is gay sauce just get partition magic.. but ive never tried resizing a partition with an OS already on it... i believe it could be impossible.. haha well good luck
I don't think it's impossible, when it is resized it would take a long time to create a new FAT (i think it creates a new FAT) and reincludes everything in the partiton
Does partition Magic explicitly support 2003? I couldn't find anything on there site so i gave a him a Powerquest link.. shoot me! There is a program called boot-it partition resizer thats even easier to use than partition magic. It's definitely not impossible.
You should be able to convert the drive from a basic drive into a dynamic drive within the disk tools with windows 2003 server, and then simply extend the partition to the extra space available. No extra software needed! Good luck!
