How to open URL in background in Powershell

I try to open an URL in background

I tried that :

$ie = new-object -com "InternetExplorer.Application"
$ie.navigate("www.bing.com")

It works ! But when I set my server url :

$ie.navigate("192.168.167.132\test.html")

the IE window appears !!!

Can you help me ?
