I have a VM running VSphere Hypervisor. It has a 20 GB capacity but is only partitioned for 16GB. I have 4 GB unallocated space. I am running low on available space and need to reclaim the 4GB. I am down to an available disk space that will not allow me to install a 3rd party partition manager. Is there a way in Hypervisor ESXi to do this? The OS is Server 2003.
