I wonder if you can help ... I was working through your Web sample ... and now I keep getting the error below when I click on a page that access the Strataframe database, Remote connections are enabled.  Can you help ?  I have SQL 2000 installed and SQL Express.  In my global asax file I added the connection string

DataLayer.DataSources.Add(new SqlDataSourceItem("", "Server = ./SqlExpress;Database=StrataFrameSample;Integrated Security=SSPI"));

.... although I don't believe I need it.  I have also successfully connected to the database using the Database connection Tool.

Just a guess, but have you tried changing this "./SqlExpress" to something like "YourMachineName/SqlExpress" ?

Actually you DO need it.  This is the connection string that establishes the connection for the application.  First, it looks like you are trying to use a named pipe, which is OK, but you need to ensure that you have permissions for this.  You are trying to connect using integrated security which is probably not going to allow named pipes through a web session be default so you would want to connect using a user name and password. 

Secondly, you said that you were using SQL 2000, but the error message indicates that you are using SQL Server 2005 and Express wasn't a 2000 product the replacement for MSDE thus the new name in 2005...so I am pretty confident you are running 2005 Express.

Finally, the message that you provided is spot on accurate when a connection fails as this is not a message that we generate.  Most times it is best to use a connection that provides a user name and password and uses TCP versus named pipes when coming from a web application:

Try something along those lines and see if you have better luck.
