Active Directory - check if a computer name is already taken

Question

When I configure a PC, one of the first steps is to assign a name to the device. I can only choose a name who belongs in "Active Directory Users and Computers". Before assigning a name, however, I need to figure out if that name is already taken by another device. To do this:

• I open PowerShell and ping a name; if something reply to the ping, that means that the name is already taken;
• I use a software named Advanced IP Scanner to examine the corporate's intranet to determine which names are already taken;
• I use an asset management tool to see which names are already taken.

Despite these checks, sometimes I assign a name already taken.

I cannot simply delete a computer name and recreate it, because our Active Directory is managed my an external provider.

I need to figure out if there is a more reliable method to check which computer names are free to be assigned. Maybe a script on PowerShell, something like this I mean.
