Whenever I setup a new XP Pro box, I always forget to change this setting. I also quite often forget how to change this setting. This is a reminder - to change the max connections that IIS on XP Pro can accept do the following:

If you have a default install of IIS, then execute the following from the command line:

cscript c:\inetpub\adminscripts\adsutil.vbs set w3svc/MaxConnections 40

Running iisreset afterward will restart IIS with the new setting.
