This error means your application is trying to connect to a SQL Express database instance on the server. SQL Express is not supported on our server for performance and security reasons. You will need to 1) Attach your SQL Express database to a SQL 2005 server 2) Update your connection string (most likely in the web.config file) to point to the SQL 2005 server rather than SQL Express Bruce DiscountASP.NET www.DiscountASP.NET

it's hard to say but try look for something like <add name="LocalSqlServer" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|xxxxx.mdf;User Instance=true" providerName="System.Data.SqlClient" /> Bruce DiscountASP.NET www.DiscountASP.NET
I did the same thing in that I set up login controls using SQL Server Express on my local machine. I uploaded it to DiscountASP and then used the new Attach MDF Tool to attach it to my SQL Server 2005 database. (Whereby this frist blew away my database wich had to be reattached.) When I use the SQL Manager Express tool, I can see the security tables in my database. I get the same error described here, when I try to use the app, however. Namely: 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) Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. I looked in the web.config to try to see where I could add the connection string and I added it just below the connection string I have in there for my access database which contains some unrelated data (and totally diffrent names). I did not see anywhere where there was a connection string for the SQL Svr Express database. Despite the connection string, after I upload the modified web.config, I get the same problem. Same exact screen. There are a number of things I do not understand. I would assume there has to somewhere be a link between a provider name andthe connection string. Where is that? How does the Connection string get related to the provider name? How do I make sure the login controls are using the same provider name? Do I have to do anything to get rid of any previous database linkage? It would be great if someone could provide the code snippits in each place that has to be changed or checked to make the generic login security work (using a placeholder like"your_connection_string" for the actual conncetion string). Any assistance would be greatly appreciated. Thanks.
I kept trying different things and something clicked along the way and it is now working, but I am not sure why. Here is my web.config: <configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0"> <appSettings/> <connectionStrings> <add name="mfcDeuConnectionString" connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\MFC\_database\mfcDeu.mdb" providerName="System.Data.OleDb" /> <remove name="LocalSqlServer"/> <add name="LocalSqlServer" connectionString="Data Source=tcp:sql2k504.discountasp.net; Initial Catalog=SQL2005_999999_xxxxxxxx; User ID=SQL2005_999999_xxxxxxxx_user; Password=xxxxxxxxxx" providerName="AspNetSqlMembershipProvider" /> </connectionStrings> <system.web> <roleManager enabled="true" /> <compilation debug="false" strict="false" explicit="true" /> <pages> <namespaces> <clear /> <add namespace="System" /> <add namespace="System.Collections" /> <add namespace="System.Collections.Specialized" /> <add namespace="System.Configuration" /> <add namespace="System.Text" /> <add namespace="System.Text.RegularExpressions" /> <add namespace="System.Web" /> <add namespace="System.Web.Caching" /> <add namespace="System.Web.SessionState" /> <add namespace="System.Web.Security" /> <add namespace="System.Web.Profile" /> <add namespace="System.Web.UI" /> <add namespace="System.Web.UI.WebControls" /> <add namespace="System.Web.UI.WebControls.WebParts" /> <add namespace="System.Web.UI.HtmlControls" /> </namespaces> </pages> <authentication mode="Forms" /> </system.web> <system.net> <mailSettings> <smtp from="[email protected]"> <network host="mail.millionfriendscampaign.com" password="xxxxxxxxx" userName="noreply" /> </smtp> </mailSettings> </system.net> </configuration> One thing I did for sure is to add the following: <remove name="LocalSqlServer"/> I also changed the Name to "LocalSqlServer". I still do not understand how the system knows what provider goes with what. I want to expand the functionality to record a "Session" record (SessionID, UserID, DateTime), but feel that if I can't figure out why I am able to work with the database, I will have difficulty doing anything else. Thanks in advance for any enlightenment.
