Hi, I have had nothing but errors when trying to install DNN 5.6.2 and or 5.6.0 ( I have tried both )

I am running SBS 2003 R2, with SP2 installed. I have .NET V2, V3.51 PS1 and V4 installed and working. I originally tried with SQL Express 2008 R2, but I kept

getting .NET SQL ZCLient errors on install ( just like many other people ) so I removed it and installed SQL express 2005. I get the same error(s), it seems

that no matter what I do, the install can not connect to the database. I have tried the link below, to no avail

http://www.dotnetnuke.com/Resources/B...

SQL Express was at least pick up with the auto install option, but Express 2005 have not picked up the auto install option in the 12 times I have tried to

install it. I can connect from a remote XP 32 SP3 machine using visual studio 2008 to the installation of SQL Express 2005 and it works fine, I can even

create a new database from VS 2008, so the logins ( SQL Server authorisation ) are working fine.

This is the error I am getting when I use the 'Typical' install option. I point it to the database I have created in SQL Server management studio express

called sever .\SQLExpress   and filename test.mdf and I have used both a normal user mapped to the test.mdf database as the dbowner and I have used the

master sa login as well, it does not work. I have also used my server name srv-xxx\sqlexpress incase there was an error with it not recognising the SQL

Express 2005 installation, which is why I am not getting the Auto install option. Before I removed the 2005 version, using 2008 R2 express, the auto option

would come up, but I still got the same error.

Connection Error(s):
Index #: 0
Source: .Net SqlClient Data Provider
Class: 14
Number: 15364

The app pool has been set to use .net 3.51 SP1

Just in case there were differences in the install between 5.6.2, I went back to 5.6.0 and the same thing happened. I have viewed the webnar for the install

and followed it.

I really do know what is going wrong. It should not be this hard.

I'm having the same problems as stuman_99 trying to install it on a development server via remote desktop. I can do the web install just fine on my machine, but when I try to install it on this server I start by getting permission problems. I've had a few guys here, who are much more technically knowledgable than I am, look at it and they can get me to the install wizard site, but it stalls out at the database and gives me the connection error with the .Net SqlClient Data Provider, Class: 20, Number: -1.

stuman_99, I followed the instructions on this website: http://www.bestwebsites.co.nz/dotnetnuke/easy-dotnetnuke-installation-guide and actually got it to work instead of getting hung up on the database screen on the install wizard. I created a new database and a new database user and when I got to the database screen I typed in the IP address of the database and the name of the database I had just created, unchecked Integrated Security and entered the username and password for the database user and clicked next and the next screen prompted me for the host login info. I hope you have success on your install as well.
