Take a look at this method if you want to use diskpart
http://vmprofessional.com/index.php?content=2k3resize You can extend with vmkfstools or just do this through the GUI. Then you use a helper VM to import the virtual disk And you can extend with diskpart.

Hi folks, I have a server (Windows 2003 std) running as a virtual machine under ESXi. Only one drive. I need to extend it. Diskpart comes up with the standard error (cannot extend this volume.). I have allocated more disk space under ESXi, and under disk manager, it shows as unallocated disk space. Any thoughts as to how I might do this? Thanks.
