The following ports are associated with file sharing and server message block (SMB) communications:

    Microsoft file sharing SMB: User Datagram Protocol (UDP) ports from 135 through 139 and Transmission Control Protocol (TCP) ports from 135 through 139.
    Direct-hosted SMB traffic without a network basic input/output system (NetBIOS): port 445 (TCP and UDP).


Use TCP/445 for your telnet test imo.

It is listening on three of the ports but rejected the telnet session on the other three.

Looks like the network is working and maybe a server configuration problem.

You won't get any response via telnet from ports that are only listening for UDP, 445 is the main one you should be concerned with getting something back from.
