Problems with the web Application Walkthrough

I am attempting to go thru the exercise outlined in:

Walkthrough:Build a Web Application That Connects to Microsoft Dynamics CRM Using Developer Extensions

https://msdn.microsoft.com/en-us/library/gg695790(v=crm.5).aspx

I can't get past the first step - Generate Early Bound Types.

I checked to make sure that Microsoft.Xrm.Client.CodeGeneration.dll was in the same folder as crmsvcutil.exe (folder=CRMSDK2011/SDK/bin). Then I navigated to the CRMSDK2011/SDK/bin folder and copied the msdos command into a command prompt and hit 'return'.

I get an error:

Exiting program with exception: Metadata contains a reference that cannot be res
olved: 'http://crm/Contoso/XRMServices/2011/Organization.svc?wsdl'.
Enable tracing and view the trace files for more information.

I tried putting the url directly into a browser and get an error that the site can't be reached.

How do I go about getting past this?

Thanks in advance.
