HttpWebRequest won't work in PowerShell without a Proxy

I am trying to get a web page using System.Net.HttpWebRequest. When there is
no web proxy in use, it won't work. However, when there is a proxy, it works
without problem. I can reproduce the problem from the command line as
follows:

PS C:\> $httpRequest =
[System.Net.WebRequest]::Create("http://www.microsoft.com")
PS C:\> $x=$httpRequest.GetResponse()
Exception calling "GetResponse" with "0" argument(s): "The underlying
connection was closed: An unexpected error occurr
ed on a receive."
At line:1 char:28
+ $x=$httpRequest.GetResponse( <<<< )
PS C:\> $x=$httpRequest.GetResponse()

But,

PS C:\> remove-variable httprequest
PS C:\> $httpRequest =
[System.Net.WebRequest]::Create("http://www.microsoft.com")
PS C:\> $httpRequest.Proxy = new-object -typename System.Net.WebProxy
-argumentlist "http://proxy.xxx.com:8080" #actual proxy name removed for
security reasons
PS C:\> $x=$httpRequest.GetResponse()
PS C:\>

I am not sure whether this is a .NET Framework problem or a PowerShell
problem. But I use the same code in a Console program compiled in Visual
Studio and it runs fine. I am using .NET Framework 2.0 for the PowerShell
script and 1.1 for Visual Studio 2003.

Thanks for any leads.

I've had no issues using WebRequest.Create to create an Http request without
using a proxy. So it works at least sometimes.

Do you normally go through this proxy for web browsing?
