HTTP 403.9 - Access Forbidden: Too many users are connected



I have created an application in VStudio. It ran nicely in debugging mode, but my computer became slower and slower as I worked until it finaly became frozen. after I manualy restarted it, the app wasn't running any more in debug and I get this execption in the browser.

  1. Only I am connected right now to the app.
  2. I have restarted the computer so there coudn't be any instance of a client connected
  3. I have removed and reinstalled the IIS

what is wrong?

    Log Parser 2.2 skipping today's IIS logs
    First, make sure your default windows script host is set to the console (cscript.exe) one.

    In a command prompt run:. cscript //h:cscript.
Next, let’s increase the connection limit to 40..
C:\Inetpub\AdminScripts\adsutil set w3svc/MaxConnections 40 
You can make the IIS connection timeout more aggressive so connections don’t last as long.. Set the default script host back to windows:.
cscript //h:wscript

Only 2 concurrent connections are allowed for localhost account.

Since you are testing the website on your server and I suppose you are using IE as your browser.. When IE requests for the web page 2 connections are maintained.

This is the possible reason for the error you are seeing..
