tip is for Windows SharePoint Services 3.0 and Microsoft Office SharePoint
Server 2007 and may apply to SharePoint Foundation 2010 and SharePoint Server 2010.
the SharePoint Technologies Configuration Wizard does not finish successfully,
the wizard will direct you to look at the following file, C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\LOGS\PSCDiagnostics_DATE_TIME_CODE.log. This file does contain information on the
failure, but a better file to check is C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\LOGS\Upgrade.log. Open the file in Notepad
and do a find for the text, [ERROR]. The error message
you find in the Upgrade.log will be much better help than the PSCDiagnostics log
for tracking down the failure issue.
