I installed a fresh copy of 7.01.02 on Server 2008R2 with SQL 2012 Enterprise.  I settled on SQL authentication and updated the Web.config.  When I launch the installwizard I see the error "No Valid default database connection detected.  Standard Database setup option is unavailable" 

I see the SQL user account I set in the web.config successfully connect to the database.  I have temporarily given every possible permission to my SQL User, Network Service and AppPool Identity but the error persists.

I was able to find a few posts regarding the issues but the only fix was to switch the appPool to classic.  Wondering if there is a different solution.

that usually indicates an incorrect connection string, or an attempt to use a netlib (such as local pipes) or a remote server. The easiest way I find to debug these is to create a UDL file (http://www.sophos.com/en-us/support/knowledgebase/65525.aspx) and use it to verify the connection. Once it works, open the udl file in notepad and check you are using the right connection string.

I followed your instructions .

Original connection string: <add name="SiteSqlServer" connectionString="Server=(local);Database=whgonline;uid=SqlUser;pwd=XXXXXXX;" providerName="System.Data.SqlClient" />

UDL Built:  <add name="SiteSqlServer" connectionString="Persist Security Info=False;User ID=SqlUser;Password=XXXXX;Initial Catalog=whgonline;Data Source=whg-mdc-db-02;" providerName="SQLOLEDB.1"/>

Same error as before.  I have even tried to install SQL express and use the default express connectionstring.  After providing what I believe to be all the correct permission to SQL Exress 2012 I still get the same error.  Anything else I can try?

After looking at the authentication logs I noticed that a Windows Use was access the database at the same time mySQL user was.  Both network service and the AppPool Identity have access too the database so I was still confused.  I figured I would try to hit the site from my PC instead of from the servers browser.  I normally use the server to see detailed errors.  Now the site is up.  Is there an explanation?  I didn't change the connectionstring.  It still uses SQL authentication.

you need to make sure you install and use TCP/IP protocol for both, SQL Server and client
