Set-NetworkAdapter fails with "The Mac Address is invalid..."

[mikelleen]

Pretty simple command:

$TargetNetworkMacAddress = '00:50:56:a1:00:00'

Get-NetworkAdapter -VM $TargetVMName | where {$_.Name -eq $TargetNetworkAdapterName} | Set-NetworkAdapter -MacAddress  $TargetNetworkMacAddress -confirm:$false

Produces error:

Set-NetworkAdapter : 7/19/2012 4:27:54 PM    Set-NetworkAdapter        The MAC address is invalid or is not in the valid range 00:50:56:00:00:00 - 00:50:56:3F:FF:FF.

Any ideas on why I am getting this error? The Mac address seems to be in the appropriate range.

The specified MAC address 00:50:56:a1:00:00 is not in the valid range 00:50:56:00:00:00 - 00:50:56:3F:FF:FF. In the specified MAC address the 'a' should be 0 to 3.

You are right the a should be 0-3, did not think of that.

Actually this looks to be the better answer and I am testing it now.

Thanks, I'll let you know if this creates any issues.
