This recently tripped me up somewhat. It should be a trivial task and in actual fact it is if you know where to specifically look in the Microsoft Dynamics CRM 2011 SDK. However, being developer minded I made the mistake of grabbing the URL CRM automatically sets for a create record form.
Typically I develop on my local machine and interact with an instance of Microsoft Dynamics CRM that’s setup within a virtual environment. At any one time I could have multiple virtual environments running. For each virtual environment I setup a unique static IP address so that my IP’s don’t conflict. Once done I wouldn’t expect there to be any issues connecting to the CRM services providing that I am supplying the correct URI and login credentials.
Microsoft hasn’t developed a 64 bit runtime of the Silverlight Framework. This means that you have to install the 32 Bit runtime in order to see your Silverlight Applications in Microsoft Dynamics CRM 2011. So when I upgraded to Internet Explorer 9 I came across a slight issues. As my Operating System is 64 bit I couldn’t use the 32 bit installer for Internet Explorer 9. If I let the auto installer do its thing I end up with the 64 bit version!
