How can I run an Azure powershell cmdlet through a proxy server with credentials?

When I run the following Powershell cmdlet (from the Azure Management Tools Snapin):

get-osversions -subscriptionId **** -certificate (get-item cert:\CurrentUser\MY\******)

I get the following error message:

Get-OSVersions : The remote server returned an unexpected response: (407) Proxy Authenti cation Required. At line:1 char:15 + get-osversions <<<< -subscriptionId * -certificate (get-item cert:\CurrentUser\MY*****) + CategoryInfo : CloseError: (:) [Get-OSVersions], ProtocolException + FullyQualifiedErrorId : Microsoft.Samples.AzureManagementTools.PowerShell.HostedS ervices.GetOSVersionsCommand

Get-OSVersions : Object reference not set to an instance of an object. At line:1 char:15 + get-osversions <<<< -subscriptionId * -certificate (get-item cert:\CurrentUs开发者_如何学运维er\MY***) + CategoryInfo : CloseError: (:) [Get-OSVersions], NullReferenceException + FullyQualifiedErrorId : Microsoft.Samples.AzureManagementTools.PowerShell.HostedS ervices.GetOSVersionsCommand

It seems that the internet proxy server here is denying the script the access it requires.

I've had a good look around on the internet and it seems that there is no easy way around this problem since this cmdlet does not have a valid "-credentials" or proxy server parameter.

I know there is a 'Get-Credential' cmdlet but I don't think it helps. How would you pass the credential to the Azure cmdlet?

Can anyone think of any way to get around this issue?..

...other than using a different non-proxied internet connection?

I'm stumped.

Many Thanks for your time.

Easier:

[System.Net.WebRequest]::DefaultWebProxy.Credentials = [System.Net.CredentialCache]::DefaultCredentials

A few customers I know were successful using the method outlined here (Supporting Basic Auth proxies). If you need other proxy types, it follows the same pattern. The nice thing about this is it does not require changing the cmdlets.
