Move site from server running IIS 6.0 to one running IIS 7.5 results in control prefixes CTL001

Question

So, my site is running fine in one environment.  It is on IIS 6.0.  CSS is working fine and I believe it is configured for .NET 2.x.

If I move the site to a server running IIS 7.5 and setup the application pool for .NET 2.x, the site renders the search control and logo, e,g, with CTL001 prefixes.  

Is there a way to make this work properly?  Thank you.

This is most likely due to a change to the ClientIDMode.
