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.
