HTTP 403.9 – Access Forbidden: Too many users are connected


have you seen this error? when opening your own web site?
and it happens that your website is hosted in windows 2000 pro or xp pro?
then the problem is obvious, the windows xp/2k pro IIS is 5.0 and 5.1, this webserver usage is locked by xp user connection configuration, which is max of 10 user connection simultaneously.
so if your webpage is accessed in over 10 connections then you’ll have the error HTTP 403.9 – Access Forbidden: Too many users are connected.
there are some suggestions on that like in microsoft website:
http://support.microsoft.com/kb/262635
that you should disable the proxy monitoring for local user, and disable keep alive in IIS option and make the session life from 900 to about 60 ms.
of course what happened if you actually publish your website to internet? the user mostly use a public address right? so the limitation of 10 simultaneous connections still apply. and if we shorten the session from 900 ms what happened if someone from the slow connection want to connect?
but once again microsoft have its own “back door” to modify the limitation, which surprisingly not mentioned as the resolution in overriding user connection limitation in microsoft support website, and in one forum (i forgot where it is), it said it is not recommended to use the software, but i haven’t seen anything bad happened to my xp IIS server, hopefully nothing bad will happen…
so follow my guide with your own risk <|-_-|>
first you must download this software from microsoft website:
meta edit 2.2
http://download.microsoft.com/download/iis50/utility/5.0/nt45/en-us/mtaedt22.exe
you can see the instruction here in microsoft support website:
http://support.microsoft.com/kb/301386
then if you open the file in c:program filesmetaeditmetaedit.exe
the windows should be like this:

then you open the W3SVC – this is the web server service- and go to max connection and you can change the value to say like 1000 (it has the max connection about 2 something’ i forgot if it is 20000 or 200000 or 2000000).
ta da you solve the 403.9 problem of your website…
but i would like to remind you that i still don’t know the side effect of this change of configuration, so do it at your own risk!
