The manual way to solve this is: Local Group Policy Editor > Computer Configuration > Administrative Templates > System > Remote Procedure Call > Change “Restrict Unauthenticated RPC clients” to configured and authenticated.

But I want to be able to script this into powershell.

You can update the corresponding registry setting. Check out the admx.help page on that policy for information about which values to use:

Set-ItemProperty "HKLM:\Software\Policies\Microsoft\Windows NT\Rpc" -Name RestrictRemoteClients -Value 2

If the reg key doesn't already exist, then you may have to create it with New-Item and/or New-ItemProperty instead.
