Local User Credential Check in windows 2012 server

Question

I am trying to validate the local user credential using the below code:

Add-Type -AssemblyName System.DirectoryServices.AccountManagement
$DS = New-Object System.DirectoryServices.AccountManagement.PrincipalContext('machine',$ComputerName)
$status=$DS.ValidateCredentials($UserName, $Password)

I am getting the below error:

Exception calling "ValidateCredentials" with "2" argument(s): "The specified network name is no longer available.
"
At line:1 char:1
+ $ds.ValidateCredentials('User','Password')
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : PrincipalOperationException

Please help me to fix this out.

Thanks in advance

Note: I am not getting this error in all the machine. Out of 87 machines i am getting this error in 12 machines alone.
