I have big problems sine yesterday!

In VS.Net Pro, from the Server Explorer, when I click the "Connect To Database" button, shouldn't I see a dialog giving me the choice of connection to another source (like Access, ...)? I don't see that dialog!

I had to do a repair installation of Windows XP and I have also done one for VS.Net when I saw that I had this problem.

Also, if I open the Server Explorer, then Servers, then my computer name. I then right-click on SQL Servers and select "Register SQL Server instance". In the dialog, the servername is already properly filled with my computer name and I leave the Instance name blank to access the local SQL Server. After clicking OK, a node appears under SQL Servers and it has a small red x on the icon. When I try to click on it, I am required to login. Whatever I try, it always fail with this error: The specified procedure could not found.

It has worked in the past and I don't know what I have changed!

Any ideaa!
