Installing MOSS 2007 on Windows Server 2008 and SQL Server 2008 - Part 6: Installing MOSS 2007

This article is a part of a series describing the installation of Microsoft Office SharePoint Server 2007 (MOSS) on a Windows Server 2008 with the newly released SQL Server 2008. Please have a look at "Installing MOSS 2007 on Windows Server 2008 and SQL Server 2008 - Part 1: Overview".

Select Advanced installation mode.
Select "Complete - Install all components. Can add servers to form a SharePoint farm."

Wait until the installation process finishes.
Note that you can download a MOSS 2007 installation DVD including SP1 from Microsoft. You need an installation source including SP1 in order to install MOSS 2007 on a Windows Server 2008.

Now you have to enter the name of your SQL Server and the MOSS farm account credentials (In my case aglaser\MOSSfarm).
If you are getting the error

"Failed to connect to the database server or the database name does not exist. Ensure the database server exists, is a Sql server, and that you have the appropriate permissions to access the database server. To diagnose the problem, review the extended error information located at C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\LOGS\PSCDiagnostics_8_13_2008_11_19_34_359_1143906485.log. Please consult the SharePoint Products and Technologies Configuration Wizard help for additional information regarding database server security configuration and network access." or

"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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)"

you have to make sure you

-have deactivated your firewall or opened the ports needed and
-that you have a working network connection to your Active Directory server. Try to ping your AD server.
