Re: telnet to exchange servers
Hi Salmanryk,
If you close those ports, user will not be able to send emails using the exchange server so the best way to go is disabling the telnet in the network computers using a GPO.
Other solution might be to upgrade all the operative systems to Windows 7 or above where the telnet application its disabled by default. Then, make sure your users are not allowed to install it and you should be able to prevent the use of the tool.
