Hi everyone, I created a web application from the Web Application Tool: something like this: www.mydomain.com/MyApps/Application1/ So my web application is Application1... I uploaded my files like this into that folder; /App_Code/ /App_Data/ --MyDatabase.mdf --MyDatabase.ldf /App_Themes/ Default.aspx Default.aspx.cs Web.config Now then... My connection string in the Web.config is: .. <connectionStrings> <add name='DSN' connectionString='Data Source=.\SQLExpress;Integrated Security=True;User Instance=True;AttachDBFilename=|DataDirectory|DigitalIstanbul.mdf' providerName='System.Data.SqlClient' /> </connectionStrings> .. I have this in my Default.asox <asp:Image ID='imgFeaturedPhoto' runat='server' ImageUrl='~/Handler.ashx' /> The 'Handler.aspx' just serves up an image from the database... So when I request the Default.aspx, I get this error message: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) Now what is the problem here?.. Any ideas? Thans
