Hi, Our site is having intermitent downtime and we're trying to find out the problem, however I require to enable the Error Trace in IIS, http://learn.iis.net/page.aspx/266/troubleshooting-failed-requests-using-tracing-in-iis-7/ However, as i try to enable the feature seems like is locked at machine.config level. I appreciate any help you can provide me with this issue. Thanks.
