SP Linkchecker object not set to an instance of an object

Apr 28, 2011 at 4:04 PM

Hello, I've installed the SPLinkchecker and can scan the root site of each web application.  When I try to scan a site collection in the web application that is not the root site collection i receive:  SharePoint.Intranet.LinkChecker.TimerJobs.LinkCheckerTimerJob Object reference not set to an instance of an object. 

Does anyone know how to fix this or have any information?  Thanks.
