You receive "The RPC Server is Unavailable" when trying to add IPs via netsh

If you receive an error when attempting to add IPs with netsh on Windows Server 2008 (this may apply to earlier versions as well), if you do not have the DHCP Client service enabled, you will receive the error:

"The RPC Server is Unavailable."

This unfortunately took many hours, including many hours from Microsoft (which were unsuccessful), to figure out. Hopefully someone finds this post and helps them out.
