In one of our prod server we recently ran into issue when we went and update the web.config and try to browse the service. We started seeing the service was not responding and getting the following warning in the application log. Our service is WCF service, BizTalk orchestration exposed as service. We have other prod server where we never ran into this issue, so what’s different with this server. After going thru lot of forum and came up on some Microsoft service pack and hot fix which related to FCN. But I don’t want to apply any patch on this server then we need to do on all the other servers too. So solution is simple, I dropped the existing website, created a new site with different name with updated web.config browse the service. Then dropped that site and recreate the original web site and it worked fine without any issue.
