Dynamics CRM 2011 using the old MSCRMService Endpoint under IFD - Impossible to connect!

Hi,

I have CRM 2011 IFD but need to use old MSCRMService temporarily.

I have learnt that we need to get a token as if we try to use the endpoint /2007/...asmx we get a 401 error.

Can someone please show me some code that works? I have spent all day trying to find this code.

I am using... but still get 401 error?
