Windows authentication works for XP but not Windows 7

I have arcgis server 10.1 with web tier security enabled. Windows authentication is the only option enabled in iis. Everything works perfectly when I connect to my services using silverlight on XP. When I connect using Windows 7 I am presented with a dialog for my username and password. This pops up for every layer accessed and then returns an error "The remote server returned an error: not found"
We are in the process of standardising all clients to Win 7 - What do I need to do to allow both XP and Win 7 clients to connect?

Best regards,
