I have an Ajax enabled web app created with Visual Studio 2005 - .Net framework 2.0. I publish this to a Windows 2003 server and everything works fine.

I now need to publish to a Windows 2008 server with IIS 7.0. Whereas before I used to publish to http:// .... (because the site on the 2003 server was Frontpage server extension enabled} I can't see how to do this in IIS 7.0 so I have published to a share on the server at \\servername\websites\nameofwebsite

When I try to run the site I get this:

Could not load file or assembly 'System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.

Any help much appreciated.
