How to extend Server 2008 partition without reinstalling or losing data

For many people, it is a headache to resize or extend a partition in Windows Server 2008, the typical examples:

I am using Windows server 2008 and a 360 GB hard disk connected, this disk is partition individual in two drives. Now the 35GB C: drive running low and I want to resize this partition. Is it possible? Please suggest.

We have a Windows Server 2008 with C: and D: drives. I freed up 40GB from D: drive, but the "Extend Volume" on the C: drive is grayed out. Can you please tell me how can I extend the Server 2008 C drive?

Good news from Microsoft is, disk management built-in "Extend Volume" feature is able to extend both data drive and system partition online. The bad is, you cannot extend the C: drive until you delete the next contiguous data partition.

Another Windows built-in utility - diskpart is neither able to extend Server 2008 partition without losing data.

The best choice to extend Server 2008 drive is 3rd party partitioning software.
