What is tlntsvr.exe?

Telnet is a network protocol used on the Internet or local area networks to provide a bidirectional interactive text-oriented communication facility using a virtual terminal connection. User data is interspersed in-band with Telnet control information in an 8-bit byte oriented data connection over the Transmission Control Protocol (TCP).

Overview

tlntsvr.exe runs as a service under the name Telnet (TlntSvr) with minimum LOCAL SERVICE privileges (predefined local account used by the service control manager) on the local PC and presents anonymous credentials on the network. This version is designed to run on Windows 7 and is compiled as a 64 bit program.
