We have recently upgraded some of our SQL servers to 2008. With that, most of the clients need to be upgraded. W ehave run into a problem. On a XP desktop with 2008 client, we are unable to modify a Stored Procedure (or create a new one) on a SQL 2005 Server. It gives the below error. We are able to creat and modify a SP on a Windows 7 desktop with the same server. Any ideas.
