I have following PS script to download file using WebClient . The download links are in a text file.

However, if duplicate is found then the code breaks with this error: Exception calling "DownloadFile" with "2" argument(s): "An exception occurred during a WebClient request." The Write-Host $newTarget value looks like this: \\NRP-12-62-3\Root\NV-RST\Southwest Projects\Marketing Analysis\Monthly Sales Reports\10-01-2015-223403\Travis, Martin_17Jul14

string url = "http://google.com/index.html"; WebClient client = new WebClient(); Stopwatch sw = new Stopwatch(); sw.Start(); string text = client.DownloadString(url); sw.Stop(); Console.WriteLine(sw.Elapsed); Stopwatch says DownloadString method takes 13-15 seconds when first called, but repeated calls take sensible amounts of time.

Try setting the proxy to null: client.Proxy = null; Your machine is configured to perform Automatic Proxy
