    Hello !

    I try to download file from site to my hardisk by PowerShell script through non-MS proxy with domain autorization. 

    $source = "http://mysite.ru/file.txt"
$dest = "c:\file.txt"
$WebClient = New-Object System.Net.WebClient
$WebProxy = New-Object System.Net.WebProxy("http://proxyserver:port",$true)
$WebProxy.Credentials = New-Object Net.NetworkCredential("user","password","domain.local")
$WebClient.Proxy = $WebProxy
$WebClient.DownloadFile($source,$dest)

    But, when I start this script, I get the error: The request failed with HTTP status 407: Proxy Authentication Required.

    I read the System.Net.WebClient reference and found that Proxy property have a type IWebProxy. But when I try $WebClient = New-Object System.Net.IWebProxy("http://proxyserver:port",$true), I get the message that PowerShell can't find constructor of System.Net.IWebProxy.

    How can I do it right ?

    Hi Andy,

    Your script works for me. Only when I put wrong crentials I get your erros.
    PS. I have too non-MS proxy and I put only user and password witout domain:

    $WebProxy.Credentials = New-Object Net.NetworkCredential("user","password","")

    The problem is solved:

    $source = "http://site.com/file.txt"
$dest = "C:\file.txt"
$WebClient = New-Object System.Net.WebClient
$WebProxy = New-Object System.Net.WebProxy("http://myproxy.com:1111",$true)
$Credentials = New-Object Net.NetworkCredential("user,"","domain.local")
$Credentials = $Credentials.GetCredential("http://myproxy.com","1111", "KERBEROS");
$WebProxy.Credentials = $Credentials
$WebClient.Proxy = $WebProxy
$WebClient.DownloadFile($source,$dest)
