Access web using Powershell and Proxy

Question

I can't seem to get access to a webpage using Powershell. I keep getting a "(407) Proxy Authentication Required". I've tried many things. I don't know what the proxy is or what kind of authentication it requires. The only thing I have access to is in IE it uses a script for configuring. I tried using some IPs from that, but no luck. Any ideas?

Here is one example of what I tried:

$wc = New-Object System.Net.WebClient $wc.Headers.Add("User-Agent","Mozilla/4.0+")         $wc.Proxy = [System.Net.WebRequest]::DefaultWebProxy $wc.Proxy.Credentials = [System.Net.CredentialCache]::DefaultNetworkCredentials $wc.DownloadString("http://stackoverflow.com") 

Answer 1

I had a similar issue and resolved it with just two lines of powershell:

$browser = New-Object System.Net.WebClient $browser.Proxy.Credentials =[System.Net.CredentialCache]::DefaultNetworkCredentials  

Hope this helps.
