Error 0x8004230f – Adjusting the Shadow Copy Treshold

When trying to configure the Shady Copy settings of a drive that is nearly full, the 0x8004230f error may occur on Microsoft Windows SBS 2011 when you try to configure the Shadow Copy settings from the hard disk in My Computer.

If you need to free up space immediately, you can run the following command from the command prompt under the Administrator account to free up space:

Vssadmin delete shadows /For=C:

Replace C: with the drive you wish to free space up on.

Please note, that the above command will delete ALL YOUR SHADOW COPIES from that drive, so ensure that you do not need them before removing them.
