How do I increase the connection limit for IIS 5.1 on Windows XP Pro?

Windows XP Professional runs IIS version 5.1, which comes with a 10 connection limit. Often that's not enough when you are testing a site from multiple browsers (or multiple locations). You can easily increase the limit to the hardcoded maximum: 40 connections.

Make a command prompt window (start, run, cnd.exe) and issue these commands.
cd \inetpub\adminscripts
cscript adsutil.vbs set w3svc/MaxConnections 40
iisreset
 

]]>The first command connects you to the adminscripts folder. The second command runs a script that sets the MaxConnections value in the IIS metabase to 40 (the maximum allowed). The third command (iisreset) shuts down and then restarts IIS.

  • Wow, great FAQ! You say that 40 is the hardcoded maximum; is this an OS limitation, or a limitation of the IIS version that comes with XP? jworden@brownsburg.k12.in.us Thanks!
