Telnet Client Missing from Windows 7, how to quickly fix this

I see a ton of people griping about the fact that telnet is missing (by default) from Windows 7.

This is actually because we (the IT industry) kept asking for thinner, more secure, etc.


This is incredibly easy to work around… you’re generally already at the command line… so from a DOS prompt all you have to do is type this:

pkgmgr /iu:”TelnetClient”

And you’ll have your telnet client back super fast! (make sure and give it a minute or two to finish, this runs silent)

You have to be a member of Local Administrators group in order to run ADMT

If you get the following error:

You have to be a member of Local Administrators group in order to run ADMT. : Access is denied. (0x80070005)

You are likely not running the command from an elevated command prompt. When you search for the error there are a lot of blogs talking about adding yourself to the domain admins group on both domains. This is true – but it is not your issue.

Re-run with elevated permissions.

(actually your first hint would probably have been that you got the error ” ‘admt’ is not recognized as an internal or external command, operable program or batch file.” and had to change to the c:\windows\admt directory)

Bulk user and computer creation in AD

If all you need to do is create a bunch of users and computers for a test environment you can use these simple little scripts at the command line – just change to your domain/OU:

FOR /L %i in (1,1,500) DO dsadd user “cn=MyUser%i,ou=MyOU,dc=domain,dc=local” -samid MyUser%i -upn myuser%i@domain.local -fn My -ln User%i -display “MyUser%i” -pwd P@ssw0rd -disabled no

FOR /L %i in (1,1,500) DO dsadd computer “cn=MyClient%i,ou=MyClientOU,dc=domain,dc=local”
