Hi David 
The best I can suggest you is to upgrade to CF 10 as CF 8 is not supported on Server 2012 : http://www.adobe.com/products/coldfusion/pdfs/cf8_systemsupportmatrix. pdf
It's better to follow the support matrix to avoid the unexpected behavior of the product as issues during development can be tolerated however issues on production are a big pain
Thanks
