Setting Connection Timeouts
Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1
Connection time-outs help reduce the loss of processing resources consumed by idle connections. When you enable connection time-outs, IIS enforces the time-outs at the connection level.
Important
You must be a member of the Administrators group on the local computer to perform the following procedure or procedures. As a security best practice, log on to your computer by using an account that is not in the Administrators group, and then use the runas command to run IIS Manager as an administrator. At a command prompt, type runas /user:Administrative_AccountName "mmc %systemroot%\system32\inetsrv\iis.msc".
Procedures

On the Web Site or FTP Site tab, in the Connection timeout box, type the maximum number of seconds that IIS should maintain an idle connection before resetting the connection.
For the WWW service, verify that the Enable HTTP Keep-Alives box is selected. For more information, see Enabling HTTP Keep-Alives.
