The Telnet Server service values are located at:

HKEY_LOCAL_MACHINE\Software\Microsoft\TelnetServer\1.0
 
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).
HKEY_LOCAL_MACHINE\Software\Microsoft\TelnetServer\1.0\Performance
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.
You must Stop and Start the Telnet Server service for changes to take effect.
