Get-NetIPConfiguration increments $Error count without posting error

Question

Hi All:
I observed that the Get-NetIPConfiguration cmdlet increments the $Error count even when successful without posting an error.
Problem Description
I'm building an application that embeds the Get-NetIPConfiguration cmdlet within a scriptmethod of a psobject. Although NetIPConfiguration appears to work just fine, it increments the error count. Here's a sample error message for the $Error variable:
Get-NetRoute : No matching MSFT_NetRoute objects found by CIM query for instances of the ROOT/StandardCimv2/MSFT_NetRoute class on the  CIM server: SELECT *
FROM MSFT_NetRoute  WHERE ((DestinationPrefix LIKE '::/0')) AND ((InterfaceAlias LIKE 'Ethernet')). Verify query parameters and retry.
At C:\windows\system32\windowspowershell\v1.0\Modules\NetTCPIP\NetIPConfiguration.psm1:207 char:44
+             $IPConfig.IPv6DefaultGateway = Get-NetRoute -DestinationPrefix "::/0 ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (MSFT_NetRoute:String) [Get-NetRoute], CimJobException
    + FullyQualifiedErrorId : CmdletizationQuery_NotFound,Get-NetRoute
This problem can be replicated on the command line using the following steps:
PS C:\WINDOWS\system32> $Error.Count
0
PS C:\WINDOWS\system32> Get-NetAdapter Ethernet | Get-NetIPConfiguration
InterfaceAlias       : Ethernet
InterfaceIndex       : 4
InterfaceDescription : Broadcom NetLink (TM) Gigabit Ethernet
NetProfile.Name      : POLLUX
IPv6Address          : 2001:db8:1::1005
IPv4Address          : 192.168.1.4
IPv6DefaultGateway   :
IPv4DefaultGateway   : 192.168.1.1
DNSServer            : 68.115.71.53
                       68.113.206.10
                       66.189.0.100
PS C:\WINDOWS\system32> $Error.Count
1
Notice the error count increments, but no error is displayed. Here's the value of $Error
PS C:\WINDOWS\system32> $Error
Get-NetRoute : No matching MSFT_NetRoute objects found by CIM query for instances of the
ROOT/StandardCimv2/MSFT_NetRoute class on the  CIM server: SELECT * FROM MSFT_NetRoute  WHERE ((DestinationPrefix LIKE
'::/0')) AND ((InterfaceAlias LIKE 'Ethernet')). Verify query parameters and retry.
At C:\windows\system32\windowspowershell\v1.0\Modules\NetTCPIP\NetIPConfiguration.psm1:207 char:44
+             $IPConfig.IPv6DefaultGateway = Get-NetRoute -DestinationPrefix "::/0 ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : ObjectNotFound: (MSFT_NetRoute:String) [Get-NetRoute], CimJobException
    + FullyQualifiedErrorId : CmdletizationQuery_NotFound,Get-NetRoute
This behavior occurs when run on the local host. When the Get-NetIPConfiguration command is wrapped in an Invoke-Command and issued to a remote server (Hyper-V Server R2), no errors are reported. If the command is issued locally on the same
server, the error count increments. Anyway, if someone would be willing to confirm this behavior and/or submit a problem report to encourage a fix, that would be great. Thanks in advance!
Have a GREAT DAY!!

Hi,
I tried that on my computer, and even got no error when running get-netroute, after run Get-NetIPConfiguration, it incresed the error count to 1. And the $error was same as yours.
I would like to suggest you also post the issue into the following link:
