HKEY_LOCAL_MACHINESoftwareMicrosoftTelnetServer1.0 Name                   Data type         Values--------------------------------------------------------------------------AllowTrustedDomain     REG_DWORD         0x00: Prevent users from logging                                         in using an account from a                                          trusted domain.                                         0x01: Allow users from a trusted                                         domain to logon. (default) AltKeyMapping          REG_DWORD         0x00: Pressing CTRL+A                                         emulates the ALT key. This enables you to                                         send an ALT combination to programs running                                         on SFU Telnet servers.                                         0x19: Press CTRL+Z                                         emulates the ALT key. This enables you to                                         send an ALT combination to programs running                                         on SFU Telnet servers.                                            DefaultDomain          REG_EXPAND_SZ     Uses the default Windows domain for                                          login authentication.  DefaultShell           REG_EXPAND_SZ     The full path of                                         the shell or command                                         interpreter that runs                                          when a Telnet user logs                                          on. The default is Windows NT                                          Command Prompt (Cmd.exe), but can                                         be set to a UNIX shell.LoginScript            REG_EXPAND_SZ     Sets the full path of a batch                                         file when a Telnet user logs on.                                          This is similar to a global                                          .cshrc file or profile in UNIX.MaxConnections         REG_DWORD         Applies only if you                                          purchase a license through                                         Services for UNIX. In Windows                                         2000, the Telnet Server service                                         has a hard coded limit of two                                         simultaneous connections. MaxFailedLogins        REG_DWORD         Determines the number of                                          unsuccessful logons before a user                                         is disconnected. (default is 3)NTLM                   REG_DWORD         0x00: Disables Windows NT                                         LAN Manager (NTLM)                                         authentication.                                         0x01: Attempts NTLM first, and                                         then uses clear text                                         authentication.                                         0x02: Uses NTLM authentication                                         only.TelnetPort             REG_DWORD         Defines the Transmission Control                                         Protocol (TCP) port for Telnet                                         connections. (default is 23)  TermCap                REG_EXPAND_SZ     Sets the full path to the                                          "terminal capabilities" file.                                          This file is similar to a UNIX                                          file, which is used to define                                          standard layouts and key mappings                                         for common emulation types (for                                          example, VT52, VT100, and ANSI).

NumThreadsPerProcessor REG_EXPAND_SZ     Determines the number of threads                                          assigned to each processor for                                          execution. The default value is                                         set to 10. The minimum value                                          is 2.
