为IIS 7.5 .NET应用安装MS SQL 2005驱动程序

Question

I don't normally do .NET development but I have a small .NET app that I need to set up on a new Win2K8 IIS 7.5 server, the SQL 2005 server is on a different box. I've tested the .NET app on an Win7 IIS 7/SQL 2005 machine and it works fine. When I run the app on the new server I get the following error:

The 'SQLNCLI11' provider is not registered on the local machine.

I googled the error and found out that I needed to install the native client drivers. I found the sqlncli.msi file on the database server and installed it on the IIS server. Same problem. I then installed the SQL Management Studio thinking that might have some drivers that it needed. Same error. I can connect through the management studio but the .NET app keeps giving me the same error.

Any suggestions?

Thank!

Answer 1

I changed the provider in my connection string from SQLNCLI11 to SQLNCLI10.
Works like a charm.
