Sharepoint Config database available in SQL but not visible from SP - OWSTimer errors

Hi,

SP has lost its connection to the Sharepoint Configuration database.

When i run the powershell command Get-SPDatabase, I dont see the Configuration database, but i can see the database in SQL. I am getting error messages on my WEb and App server every 15 minutes from the SPTimer Job - There was an internal error invoking the timer job '{FD730E80-C470-4D92-B0E5-F57C98ABDF4A}' for service '{00000000-0000-0000-0000-000000000000}'.

So I tried the following command to reconnect to the config database to the Farm

Connect-SPConfigurationDatabase

cmdlet Connect-SPConfigurationDatabase at command pipeline position 1

Supply values for the following parameters:

DatabaseName: SHAREPOINT

DatabaseServer: SW00xxxx

Passphrase: **********

WARNING: This machine is already joined to an existing farm. Use the Disconnect-SPConfigurationDatabase cmdlet to remove this machine from the current local farm. If you have recently disconnected this machine from a farm and are still seeing this error, you may need to restart the SharePoint 2010 Management Shell to refresh cached data.

I havent tried the DisConnect-SPConfigurationDatabase option incase i have a problem reconnecting it again, and I am able to login to Central admin and all looks fine except for when i choose Manage servers on Farm and i get a Runtime error.

It looks like I can reconnect the configuration database by running a PSCOnfig.exe command as outlined in the attached link but as this is a Production server i am reluclant to run it.
