Despite that I’m a regular reader of this great forum, this is my first post on it. I believe that this community can help me with the following problem that I have.
I’m trying to publish an ASP.NET website over an IIS 6.0 (Windows 2003 Server), and I have some troubles trying to connect to the database. Curiously, I have installed another ASP.NET website into the same IIS 6.0 with the same properties and security parameters and can connect without problems with the same database. The application that works fine is almost the same that the one that can’t connect with SQL Server (actually is the same but with several modifications).
I’ll enumarate some information related to the problem:
- S.O: Windows 2003 Server
- SQL Server Engine: SQL Server 2008 SQL Server accept remote connections? Yes.
- ASP.NET version: 2.0.50727
- The connections via TCP/IP are enabled to the SQL Server instance? Yes.
- The corresponding user that I have in the connection string, actually exists into the database with the “owner” role? Yes.
- ORM Tool used: nHibernate
I get the following error when I try to run the aplication into the browser:
Error while establishing a connection
to the server. When connecting to SQL
Server 2005, this failure may occur
because the default settings SQL
Server does not allow remote
connections. (provider: Shared Memory
Provider, error: 40 – Could not open a
connection to SQL Server)
In order to isolate the problem, I made some test. For example, using the web app that works fine I can connect without any problema with the database that uses the web app that can’t. With this evidence I concluded that the problem is within the web app and not into the SQL Server instance. I also google it my problem but sadly I can’t find nothing usefull to solve it.
If someone can help me I’ll appreciate that.
Thank you so much for your time!
I’ve found the problem. In order to solve it, I was install in a virtual machine the same OS (Windows 2003 Server) and IIS (6.0). In this clean enviroment, I’ve found that the changes that I made in the home page was the problem. This aspx page has Web Parts that I’ll investigate to know why is causing troubles with the database connection. I navigate to another page of the web application and it can connect with the database and retrieve information without any problem..but when I try to reach the home page the aplication colapse because of the problem that I tell you in this thread.
I’ll post more news about this problem when I resolve it completely
Thanks for your assistance and time.
