C# 2008 error

Question

I have a question about using the visual designer in a C#.net 2008 desktop application. I am wondering if the  error listed below is generated somehow in visual studio.net 2008? If so, can you tell me what to look at to resolve the problem?

If the issue is not generated by Visual Studio.net 2008 professional edition, can you tell me what else I should look at to try to resolve the problem? (The network administrator here says I do have access to the correct database remotely.)
