How do I extend an XP System Partition?

Hi

When I built my Windows XP machine, I installed XP on it’s own partition (3GB in size) and then created another partition (20+ GB in size) for everything else.I then converted the partitions to Dynamic Disks.

Fairly predicitivly XP has grown and I am now running out of room. Is there any easy way of increasing the size of the System partition to say 5GB, without rebuilding the machine, or buying Partition Magic?

Thanks

Gouldy.
