In example below it will expand the disk by 10GB, if no size is specified all available space will be allocated to the partition. Keep in mind that Windows 2003 doesn't allow to expand system volume.
This can be via GUI just with right click - expand if there is free space right after it.

If the Recovery partition is between the volume and the empty space, you can delete and recreate it:
Disable the existing Windows Recovery Partition by running:
reagentc /disable
Use Diskpart to remove the recovery partition
DISKPART > list disk DISKPART > select disk # (where # is the disk needing the recovery partition removed) DISKPART > list partition DISKPART > select partition 4 (where 4 is the recovery partition) DISKPART > delete partition override (to force deletion of the recovery partition)
Expand the disk using Disk Management, leaving ~1 GB at the end of the drive for recreating the recovery partition
Create New Simple Volume for Recovery, NTFS, no drive letter Use Diskpart to set the recovery partition attributes
DISKPART > list partition DISKPART > select partition 4 (where # is the new recovery partition)
For GPT disks run:
DISKPART > set id=de94bba4-06d1-4d40-a16a-bfd50179d6ac DISKPART > gpt attributes=0x8000000000000001
For MBR disks, run set id=27
Re-enable the recovery partition by running:
reagentc /enable
