DiskPart commands help you to manage your PC's drives (disks, partitions, volumes, or virtual hard disks). 
Before you can use DiskPart commands, you must first list, and then select an object to give it focus. 
When an object has focus, any DiskPart commands that you type will act on that object.

Address discoverability issues
The Windows Time service cannot discover the configured time source peer. Ensure that the time source 
peer is online and available. There should be other events in Event Viewer that indicate that there is 
a problem locating a domain controller. Review those event messages and resolve them as appropriate. 
When you have resolved them, resynchronize the local Windows Time service with the time source peer. 
Perform the following procedure on the computer that is logging the event to be resolved.

To perform this procedure, you must have membership in Administrators, or you must have been delegated 
the appropriate authority.

To resynchronize the client with the time source peer:

Open a command prompt as an administrator. To open a command prompt as an administrator, click Start. 
In Start Search, type Command Prompt. At the top of the Start menu, right-click Command Prompt, and 
then click Run as administrator. If the User Account Control dialog box appears, confirm that the 
action it displays is what you want, and then click Continue.
At the command prompt, type w32tm /resync, and then press ENTER. The command output indicates 
whether the synchronization was successful.
