WSUS installation on Sql server

Hi,

I am installing wsus on a windows 2003 x 64 server called server02
I also have a server01 which runs mssql 2008 standard.

When I install wsus everything goes fine. When I put server02 as remote db server it says ok.

A few seconds after the installation wizard closes the follow popup occurs.

"An error occurred when trying to preform a database operation, and the wizard must be closed.  You may restart the WSUS Server Configuration Wizard from the Options page in the WSUS 3.0 console." See Attachement A

I then launch the WSUS management console, and it is not connected to the server (NEO), so I click on connect to server, type NEO in the server block and use the drop down to select port specified during the installation.  When I click ok I get the following error.

'Cannot connect to 'server02'. SQL server may not be running on the server.

Here are the step I have taken to try and resolve the problem  Unsuccessfully

Registered SPN for the SQL instance - http://support.microsoft.com/kb/909801
The best I've tried.

I also found this:
https://www.experts-exchange.com/questions/23845370/WSUS-installation-fail-when-connecting-to-Remote-SQL-2005-Server.html

It is exactly my problem but I ain't so advanced user so the solution seems complicated.


Here are a couple of items from the event logs:
