I have a server on VMware that I set up with the C drive too small.it is currently set up with Windows 2003 which I know I cannot expand the C drive with that OS.can it be done with Windows 2008 R2? I have seen some articles which say that it has to be done with a third-party application. Which third-party applications would do the best job and also be free? Or put another way, not as a loaded question, can the C drive the expanded while upgrading the server OS?

With 2008 it can be done without problems using diskmanagement, as long as the free space is on the same disk as the one you are expanding, and it comes right after the partition you are expanding.

Since on VMware it doesn't make much sense to partition a virtual disk into more than one partition, that should be no problem there. First just assign more space to the virtual disk in the properties of your VM, then start the VM and use diskmanagement to expand C:...

You can expand Windows 2003 C drive offline, just increase the vmdk size from VMware, reboot the machine using WINPE boot disk, go to command prompt, run diskpart
select appropriate disk and type expand. You can use any boot disk which supports the file system on the disk and has utility to expand disk, try booting with windows 2003/2008 in repair mode command prompt.

Windows 2008 allows expanding C drive online.

Another option is to attach the disk to another VM and expand disk from there using diskpart.

I did allocate the space on the vmdk. and it is on the same disk part. I'm going to upgrade the OS and see if that will work. thanks.

Are your AD admin tools letting you down?

Managing Active Directory can get complicated.  Often, the native tools for managing AD are just not up to the task.  The largest Active Directory installations in the world have relied on one tool to manage their day-to-day administration tasks: Hyena. Start your trial today.

It will, you will just need to use Disk Management as stated above.  Open Server Manager > Configuration > Storage > Disk Management > Right Click the C drive (if you truly have space to extend to and it is right after the C drive it will be black and say unallocated) and select Extend > the rest is simple :)

No need to upgrade the OS, it can be done for FREE, whilst the VM is live! (no downtime!) in less than 30 seconds.....

Please see my EE Article, it can easily be expanded in real time, with no downtime!

HOW TO:  Resize a VMware (VMDK) Virtual Disk

see and use Dell ExtPart!

The Dell Extpart utility will expand boot drives on WindowsXP/2000/2003 without downtime.

Please ensure you have a full backup, before any disk or partition management.
