Extend System Partition C Drive Windows 2003 Server

"Is there any solution for C drive system partition resizing on Windows Server 2003? I need to extend C drive system partition to fix the low disk space problem, but it failed when I run Diskpart to extend C drive on Server 2003. I know I can uninstall some programs to free up space, but it is not a good solution for me because all the programs and data on C drive are important. I want to look for a way to extend C drive without reinstalling system or reformatting disk."
