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 safest and most popular server partitioning software, NIUBI Partition Editor is the only program that integrated Roll-Back technology to ensure 100% data safety. It automatically roll back the server to the status before resizing in ONE second, if any software error or hardware issue such as power failure occur during resizing. So I always recommend this tool to resize Windows server partitions. I've tested it on most of the Windows Server editions, every time, it returns with successful message.
