We were trying to apply Service Pack 2 to our MOSS 2007 installation. Once we installed the service pack we tried to run the config wizard and it would get to task 5 and the configuration would fail. Then we would get the following events in the Event Viewer:
Event ID: 100
Source: SharePoint Products and Technologies Configuration Wizard
Description:
Configuration of SharePoint Products and Technologies failed. Configuration must be performed in order for this product to operate properly. To diagnose the problem, review the extended error information located at C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\LOGS\PSCDiagnostics_7_20_2010_8_9_2_615_239088506.log, fix the problem, and run this configuration wizard again.

Event ID: 6066
Source: Office SharePoint Server
Description:
Couldn’t Register with Load Balancer: Unable to connect to the remote server
Event ID: 6102
Source: Office SharePoint Server
Description:
LoadBalancer.RegisterLauncher failed: Unable to connect to the remote server
All of these were caused by one registry key:
HK_local_machine\software\microsoft\shared tools\web server extensions\12.0\wss\services\
Under that key, find the service that it was failing on and delete that key. In our case it was Windows SharePoint Services Search. We backed up that registry key and then deleted it. We reran the configuration wizard and it worked.
I hope this helps!!
