I am running powershell:
Get-NetIPInterface :
PS C:\Users\Administrator> Get-NetIPInterface
"Get-NetIPInterface" cmdlet
:1 : 19
+ Get-NetIPInterface <<<<
+ CategoryInfo : ObjectNotFound: (Get-NetIPInterface:String) [], CommandNotFoundException
+ FullyQualifiedErrorId : CommandNotFoundException
but the above does not recognize the "Get-NetIPInterface" entry as the name of a cmdlet, function, script file, or runnable program. Check the spelling of the name, and if you include the path, make sure the path is incorrect.
