When installing SharePoint 2013 in single server
mode on a machine that is not connected to a domain , you might want to use SQL server 2008
R2 or SQL server 2012 instead of SQL server express. But SharePoint 2013
configuration wizard wouldn’t allow you to do so and will throw an error stating
local system accounts can be used only on standalone mode.
To work around this SharePoint validation and
install SharePoint 2013 with a local system account and still use SQL Server, we will have to use the
PowerShell command New-SPConfigurationDatabase to create a new SharePoint configuration
database and rerun the configuration wizard. The New-SPConfigurationDatabase command
will prompt for database name, server and farm credentials as user input. When
prompted for the farm credentials you can supply the credentials of the local system account. The command will create a SharePint 2013 configuration database in the SQL
server you have provided.
Once the SharePoint 2013 configuration database is created,
you can re-run the SharePoint configuration wizard again and will notice the SharePoint 2013
farm is created and you will be able to proceed with the installation.
