Additional considerations

  • Tlntadmn.exe must be run at a command prompt that was opened by using the Run as administrator option. If you do not run it at an elevated command prompt, you receive an Access is denied message.

  • The Tlntadmn.exe tool is installed with Telnet Server, so might not be present on a computer that does not have Telnet Server installed.
