Question

After a system crash I had to reinstall WebMatrix, the installation went fine, then, I choose the DotNetNuke communauty standard like I did last week. However, when during the installation in the configure database section, I have this error:

Connection Error(s):
Index #: 0
Source: .Net SqlClient Data Provider
Class: 20
Number: -1
Message:

I tried to unistall web matrix and reinstall it and I have the same error, I would like to find the solution as soon as possible to continue my site development.

Thank you

Hi,

 

I would suggest you to check if TCP/IP is installed for client as well as SQL server and you have enabled remote connections for it.

Hi,

Check that FW is open for port 1433.

You can use the Administrator Tools and SQL Server Configuration
