ASP.NET C# web application to connect to SQL SERVER 2000 database

[jojo41300000]

Hi,

I have a problem with database connection to SQL server 2000 from ASP.NET. When I try to connect, it give me the errors.
But, When I try to connect to SQL SERVER 2005. It works fine.

Any ideas what the problems might be?

Thanks.
Jason.

Your connection string?

Or maybe the permissions set up on the sql2000 don't allow for you to connect to it.

What error(s) are you getting?

The errors I am getting is:
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: TCP Provider, error: 0 - No connection could be made because the target machine actively refused it.)

Sounds like the settings of the SQL server don't allow remote connections.
You should go through all those permissions and set up everything.

I tried all the permission setting, but it still won't work.

Is this the reason two database servers (2000 & 2005) installed on the same server?
My OS is Window Server 2003 Enterprise x64 Edition.
MS SQL SERVER 2005 is 64 bit version and MS SQL SERVER 2000 is 32 bit standard edition.

Any ideas what wrong with this setting?

Thanks.

two different databases will have two different instances.

You may need to go to the surface area configuration and change settings to allow Tcp IP connections too

The database might not allow windows authentication, and you may be trying to use that in the connection string.

I used sql authentication. But there is no surface area configuration in SQL server 2000. Instead, I found server network utility and client network utility.

Actually, I used mostly sql server 2005, and i never used sql server 2000 before.
I change some of the setting in server network utility such as adding TCP/IP, Name Pipes and setting the port number to 1433 because i found that the default port number is set to 0.

I am Not sure of the settings in Sql Server.

However since this topic is regarding the setings with Sql Server I will move the topic to the Sql Server Group where experts there will be able to help you better.
