Error failed to connet to the configuration database: an exception of type system.argumentnullexception was thrown. additional exception information: value cannot be null parameter name: service.

I was adding a new WFE in an existing SharePoint farm and when I ran the configuration Wizard got the error:

 Failed to connet to the configuration database: an exception of type system.argumentnullexception was thrown. additional exception information: value cannot be null parameter name: service.

I figured out we moved our database servers from old to new sometime back and the configuration database had entries for the old database server name.

Solution 1: Created SQL Alias on the WFE server pointing to new databse server and ran the configuration wizard worked all good for me

Click on the below link to check the steps on how to create an SQL Alias

Solution 2: If the first one didn’t work, you may have to create a new configuration database but that has its own dependencies. Number of Solution packages you have , settings etc. it’s an addition overload but may have to do this if SQL Alias doesn’t help.

Login to the SharePoint Server

Click on All Programs > Microsoft SharePoint 2010 Products

Launch SharePoint 2010 Management Shell

Run the following command

New-SPConfigurationDatabase

This will ask for following details:

Database Name: New Configuration Database Name

Database Server: Database Server Name

Prompts for Farm Credentials, enter the same

Now run the Product and Configuration wizard this will solve the issue.
