Seems like a connection issue. You can use the Data link properties to find if the connection is fine. Do the following: Create a blank notepad and rename it to "X.UDL" Double click to open it Under connections tab choose the server name/enter the name use the correct credentials and DB Click OK to save it. Now open the file in Notepad and compare the connection string properties
