I turned on IIS failed request tracing to troubleshoot another issue and noticed that every 30 seconds i'm getting a 404 from the same user. The site that it is attempting to access does not exist in our production environment. I figured it could be related to some timer job but i'm not sure what to check. I did notice they were listed in BCS and had a connection setup but to a different site.
Does anyone know how i could go about troubleshooting this to find out what is causing this ID to repeatedly try to access this nonexistant site?
