As with SSH, Detail Discovery with Telnet is based on accessing the managed host with a user name and
password that it recognizes. The considerations regarding the choice of user account and privileges are the
same as those for SSH, described in "Detail Discovery with SSH" on page 38.
Configuring the Windows Telnet server
Certain operating system settings must apply for a Windows host to be accessible with Telnet. Depending on
the specific edition of Windows and on the existing configuration, any of the following configuration
modifications might be necessary.
I Ensure you have local administrator permissions on the machines you are performing these
MPORTANT
procedures on.
To start up the Windows Telnet Services automatically using Windows
1 From the Windows Start menu, navigate to Setting > Control Panel > Administrative Tools > Services.
2 Locate and right‐click Telnet service.
3 Ensure the startup type is Automatic and start the service if it is not already started. This change is
required in most Windows editions.
To start up the Windows Telnet Services automatically using a command line interface

On a local machine, type:
sc config TlntSvr start= auto && sc start TlntSvr

On a remote machine where COMPUTER is the remote computer name or IP address, type:
sc \\COMPUTER config TlntSvr start= auto && sc \\COMPUTER start TlntSvr
To log in to a machine using Telnet, you need to be listed as a member of either the local TelnetClients group
on that machine, or as a member of the domain's TelnetClients group.
To modify users and groups using Windows
1 From the Windows Start menu, navigate to Setting > Control Panel > Administrative Tools > Computer
Management > Local Users and Groups > Groups.
2 If the TelnetClients group exists, double‐click TelnetClients. TelnetClients Properties window appears.
3 Click Add to add relevant user as its members.
4 If the TelnetClients group does not exist, create a new group with the name TelnetClients, and then add
the user to it.
Creating a Local TelnetClients Group
If you want to add a user to the local TelnetClients group, but no such group exists yet, you can simply create
a new group by this name. This operation is automated using VBScript or Jscript. Use the following
commands:
computer = "COMPUTER"
user="USER"
domain="DOMAIN"
Set objGroup = GetObject("WinNT://" & strComputer & "/TelnetClients")
Set objUser = GetObject("WinNT:// " &
objGroup.Add(objUser.ADsPath)
I In some editions, particularly XP Pro SP1 and later, remote access by local users is always treated
MPORTANT
as if the "guest" user is involved. This extra security measure might cause Telnet (and also WMI) to fail with
local users, but it has no effect on domain users.
