Windows Server - Unable to extend volume - There is not enough space available on the disk(s) to complete this operation

Came across this issue today on a virtual machine running in a VMware environment. After allocating additional hard disk space to the virtual machine (running Windows Server 2012), the following error appeared when attempting to extend the hard disk;



"There is not enough disk space available on the disk(s) to complete this operation"

Even though the space was showing as "unallocated" in disk management, this error still appeared when trying to extend the volume.

The fix - turns out it was quite simple. From within the Disk Management utility, go to Action > Rescan Disks then try running the extend disk again.

VMware Workstation - Internal Error when Starting Virtual Machine (VM)

Upon opening VMware Workstation and attempting to power on any virtual machine I occasionally get the error below, stating "Internal Error."



The fix for this in my experience has been to start the VMware Workstation Server service. To view your services press the Windows Key + R (to open the Run prompt) then type services.msc and press Enter

As you can see, even though it is set to "Automatic", for whatever reason it doesn't always start automatically - usually after the computer has been restarted.



Simply right click the service and select "Start". Once the service is started you should be able to power on your VM's from VMware Workstation.
