An update conflict has ocurred, and you must re-try this action

This error would appear after a disaster recovery of a whole farm, including the Configuration Database.

The point is that you have to rebuild all the Sharpoint Jobs Definition, which are stored in System Drive:\Documents and settings\all users\application data\Microsoft\Sharepoint\config\GUID Where GUID is the Configuration Database ID, if there's no GUID folder, you must create it. You can check the GUID in HKLM\Software\Microsoft\Shared Tools\Web Server Extensions\12.0\Secure\ConfigDB.


To rebuild all the Jobs Definition you should do the following:

1. stop the Windows Sharepoint Timer Service
2. Delete all existing XMLs in SystemDrive\documents and settings\all users\application data\microsoft\Sharepoint\config\GUID, if does not exist create it as shown before.

3. Start te Windows Sharepoint Timer Service.

You should see now all the XMLs refreshed.
