They can be found here in the SQL Server 2008 R2 Feature pack. You don’t need to download and load the entire feature back, just scroll down and you will find the driver here.
Take an inventory of your connections and make sure you have the native drivers for all that exist, they are faster then using generic windows drivers.
Strip the SQL out of DESKI and run it via the SQL Server Management Studio 2008 R2 to find out where the problem is.
Then using those findings you might have to adjust the Universe. This is not unusal when making a transition from one release to another, just extremely annoying!!
