I have the following code on startup
Dim props As New Collections.Specialized.ListDictionary()
_channel = New HttpChannel(props, New SoapClientFormatterSinkProvider(), New SoapServerFormatterSinkProvider())
The virtual directory is set to Read and the authentication and access control is set to Integrated Windows authentication, the problem is this works fine for the read but when I try and call one of the dlls to write something I get an access error. The only way I seem to be able to overcome this is by setting Enable Anonymous Access and specifying myself as a user.
