'RPC Server is unavailable' error but script still appears to work

Question

$computer = get-content C:\test\DNS_Server_Name.csv
$NICs = Get-WMIObject Win32_NetworkAdapterConfiguration -computername $computer |where{$_.IPEnabled -eq “TRUE”}
  Foreach($NIC in $NICs) {

$DNSServers = “198.102.234.125",”198.102.234.126"
 $NIC.SetDNSServerSearchOrder($DNSServers)
 $NIC.SetDynamicDNSRegistration(“TRUE”)
}

Getting error "RPC Server is unavailable". However, the script still inputs the DNS server as needed. I ran this with only one server name in the csv file. Any idea why I'm getting this error even though it still seems to work?

Break down your script. Run each line independently. Check the output. We cannot debug it for you. — marsze, Mar 19 '19 at 15:29

Your script still runs because the Get-WMIObject cmdlet is not terminating, check this article to understand Non-Terminating Errors in PowerShell

If you want to stop the script when Get-WMIObject generates an error, just add –ErrorAction Stop

$NICs = Get-WMIObject Win32_NetworkAdapterConfiguration -computername $computer –ErrorAction Stop | where {$_.IPEnabled -eq “TRUE”}

If you want further informations about the error "RPC Server is unavailable" itself, you may want to check that the "Windows Management Instrumentation (WMI-In)" rule is enabled in the firewall for each remote machine, as described in this answer.
