Simple TCP/IP Services (System Services for the Windows Server 2003 Family and Windows XP Operating Systems)

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2

Service Name: SimpTcp

Executable Name: Tcpsvcs.exe

Log On As: NetworkService

Description: Simple TCP/IP Services implements support for the Echo, Discard, Character Generator, Daytime, and Quote of the Day protocols.

  • Echo (port 7, RFC 862) This protocol echoes back data from any messages it receives on this server port. Echo can be useful as a network debugging and monitoring tool.

  • Discard (port 9, RFC 863) This protocol discards all messages received on this port without response or acknowledgment. It can serve as a null port for receiving and routing TCP/IP test messages during network setup and configuration or, in some cases, it can be used by programs as a message discard function.

  • Character Generator (CHARGEN) (port 19, RFC 864) This protocol sends data made up of the set of 95 printable ASCII characters. It is useful as a debugging tool for testing or troubleshooting line printers.

  • Daytime (port 13, RFC 867) This protocol returns messages containing the day of the week, month, day, year, current time (in hh:mm:ss format), and time-zone information. Some programs can use the output from this service for debugging or monitoring variations in system clock time or on a different host.

  • Quote of the Day (port 17, RFC 865) This protocol returns a quotation as one or more lines of text in a message. Quotations are taken at random from the following file: systemroot\System32\Drivers\Etc\Quotes. A sample quote file is installed with Simple TCP/IP Services. If this file is missing, the quote service fails.

To find RFC standards, see the Request For Comments (RFC) link on the Web Resources page at http://technet.microsoft.com/windowsserver/bb633748.aspx.

After this service is installed and started, all five protocols are enabled on all network adapters. There is no provision for selectively enabling specific protocols or enabling this service on a per–network adapter basis.

Stopping or disabling this service has no effect on the rest of the operating system.

You should not install Simple TCP/IP Services unless you specifically need this service to support communication with other systems that use this protocol service.
