XMLHTTP Problem

i have set up an asp application that querys a web service for exchange rates, i am using the XMLHTTP object to screen scrape the results page.

it all works fine at home but at work i the following error:

msxml3.dll (0x800C0005)
The system cannot locate the resource specified.

i have tried using proxycfg.exe to specify the companys proxy server address but still get the error.

Here is the part of my code that i am recieving the error with.

URL="http://www.webservicex.net/CurrencyConvertor.asmx/ConversionRate?FromCurrency=GBP&ToCurrency=EUR"
Set xml = Server.CreateObject("Microsoft.XMLHTTP")
xml.Open "GET", URL, False
xml.Send
xmlout = xml.responseText
Set xml = Nothing

does anyone have any ideas i could try?

thanks
