disabling a port

[jakess]

How do i disable the service or aplication using port 25 on a normal NT server.According to winnt\sytem32\driver\etc\services is the port 25 allocated to SMTP but our Exchange server is on a different server.

Is your server responding to port 25? if it is then there is a service setup to use that port. You can check it out by opening a telnet session and attempting a connection on port 25, if your telnet session connects then your server has a service installed using Port 25. Installing IIS will enable SMTP services on the server, going into the IIS manager you can shut down the SMTP service and prevent it from starting if the server is ever rebooted. You can also check in the Services tab in the control panel for any SMTP service. Basically what you need to do is shut down the service (or remove) that is answering on port 25.
