Extend system volume

[Guest]

We have a windows 2000 server std, with a physical harddrive of 8 GB, but
only 4 GB are used today for the OS and the rest is unallocated. This disc is
a basic volume. I wonder if there is some way to extend the system volume
with the unallocated space?

Partition Magic or the like, or convert to dynamic disk.(See Help)
