IIS Error codes

Why does every error in IIS come up as Service Unavailable, Unspecified Error. The only way to find out is in the event viewer and why have a status column if it doesn't tell you anything specific...

Hello,
In IE, can you make sure the option Show friendly http error messages (IE->
Tools-> Internet Options-> Advanced tab) is unchecked? This will ensure
that instead of getting a general error message you see the exact http
error code. Also, you can look in the IIS logs
(C:\windows\system32\logfiles folder) for the error code. Then you can
refer to http://support.microsoft.com/default.aspx?scid=kb;en-us;318380 for
the description of those codes.

A Service unavailable error is generally received when the application pool
serving the website is stopped (and hence there is no worker process to
handle the requests).

Hope this helps!

Thanks,

IIS logs information in several places, depending on usage:
1. Eventlog is the most high-level, "get your attention" sort of
information. It may or may not include all necessary information to resolve
a problem
2. IIS Web log contains necessary details related to handling a request
3. HTTP Error log contains necessary details related to Connection and
low-level HTTP parsing.

Between these three logs, you can determine:
1. Where did the request end up -- was it rejected based on connection
characteristics or invalid HTTP semantics (logged in #3), or did it get
handled as a request and generated a response of some sort (logged in #2)
2. Anything wrong that could prevent request handling (logged in #1)
