What is the easiest way to track or view Urls 404 (Not Found) requests in Windows 2003 IIS-6? We are moving to a new CMS, and we are using ISAPI Rewrite to redirect old Urls to the new Urls, but we want to make sure we are not missing important Urls slipping through the cracks. Is there way to record each 404 Url in a text file somewhere? We are using Windows Server 2003 IIS-6. Can IIS do this? Maybe we need a tool? Custom code? Thanks.
