: How can IIS 7.5 have the error pages for a site reset to the default configuration? A mishap occurred with web.config to accommodate a subsite existing. I made use of “<location path="."

@Ravi8258870

I've been able to reset a lot of my site's values using appcmd, but I had to dig into specific configurations I wanted to change, which I'll describe a bit below. I know for sure that this works with IIS 7, but I'm not 100% certain whether it passed on to 7.5 so YMMV.

appcmd isn't in my cmd path on any of my installations (though these machines are 2k8sp2) - anyway, from cmd prompt as administrator type:


cd %windir%system32inetsrv


then to get a nice set of examples type:


appcmd reset config /?


and to see which settings you want to reset, type:


appcmd reset config /section:?


The /section:? will give you a big dump, so I dumped it to a text file for my personal needs. You'll end up with up everything in the configs in the namespace system.web, system.webServer, system.net and a handful of others.

The command I ended up using (I needed to reset my httpErrors) is below:


appcmd reset config /section:httpErrors


I hope that's helpful! More info on appcmd here:

Nested directories can have their own web.config file, but like CSS files the rules you set cascade down.

For sub directories with their own web.config settings, Best practice is to:


Override rules you set in root web.config file by setting them as off or to the value you need.
Use applications (similar to virtual directories) instead of actual directories. The applications will not inherit parent rules.
