Hi friends I just upgraded to Windows XP to a new version called Service Pack 3. I do not see much change, although the upgrade was necessary for me, so you can install. Net 2008 and SQL Server 2008 on my pc. And after the installation everything was working well. But recently when I tried to run an error check system always displays an errors in a file called wiatrace.log, I have no idea what this file is and how to correct file.
