Windows 2003 Server R2 partition resizing software

Some people may heard of Diskpart and want to resize partition with this utility, but due to Diskpart limitations, I won't recommend it to resize Windows Server partitions. Third party partition software is much better, as you can shrink and extend any partitions without any limitations, easier and faster.

To Windows Server, data security is the most important aspect when selecting a partition tool, some unreliable partition software are very likely to cause system boot failure or data loss.

As the most popular utility, Aomei Partition Assistant Server is not only reliable itself with built-in Enhanced Data Protection technology, but also integrated Disk/Partition Copy to keep data intact while resizing.

I've tested it on most of the Windows Server editions, every time, it returns with successful message.
