Extend System partition in Windows Server 2003 VMware can improve performance both in VMware and real machine, because VMware shares memory card and processor. So when low disk space warning shows in Server 2003 VMware, it's time to extend system partition and fix this problem, if you ignore this issue, server will become slow or even no response to each single click, not only to the VMware but also infect real machine.

For example, if you install VMware in D Drive with other programs, file explorer in D Drive will crush and other programs cannot be opened smoothly like usual, hard drive in real machine reading and writing speed will decline sharply.

You can extend the whole disk size using VMware settings, but system partition cannot be easily extended in Server 2003 disk management, you had to use diskpart command to extend system partition again. Actually, with server partition software's help, you don't have to reboot server 2003 again and run diskpart tool.

Extend System partition in Windows 2003 VMware using Partition software.

Server Partition Software, Partition Expert Server Edition, runs perfect in Windows Server 2003, especially when server disk management has no way to extend volume, shrink volume, or move free space functions. The following are steps to extend system partition of Windows 2003 in VMware:

  1. Download Partition Expert, you can download the file in real machine, and paste it to VMware, that's faster than downloading files in VMware; Run Partition Expert;
  2. If you already added new size to virtual disk, you can directly click C Drive, and click Resize/Move Volume to extend C Drive; if you have free space in D Drive, you can click D Drive and Resize it;
  3. Resize D Drive is to make free space it, unallocated space to be more specific, when this space is created, click C Drive and Resize it;

NOTE: before doing anything related to hard drive, no matter in real machine or in VMware, it is highly recommended to do a backup on important stuff.
