TCP/IP Queue

Applies To: Windows Server 2003, Windows Server 2003 with SP1

At the TCP/IP layer, high-priority threads respond to client requests by validating that the server is or is not accepting and processing requests. If the server is accepting requests, the thread maintains the customer connection and attempts to hand off the request to HTTP.sys. The only reason you might need to adjust the TCP/IP queue is if users cannot connect to your site on the Web. Monitor the TCPv4\Connection Failures and TCPv4\Connections Reset counters (for TCPv6, use the same counters for the TCPv6 object). If the Connection Failures and Connections Reset counters increase steadily, examine your TCP/IP settings. For more information about TCP/IP, see Help and Support Center for Windows Server 2003.
