    Start with some basics:

    1) Are you 100% sure you assigned the same IP address AND netmask to the
    NIC? Did you also check the netmask and assigned IP on the PC's you are
    trying to connect with?

    2) Can you ping and FTP from one of the client PC's? Important - can you
    STILL ping the address WITH the UW server UN-plugged from the network
    (oh-oh dup IP number on the network)?

    3) Is there a gateway or sub-net bridging involved?

    4) Does your Telnet client use the machine name or the actual IP address
    of the UW server? (try the actual address if it uses a name)

    5) Do you have the DNS servers and the resolution ordering id'ed in
    /etc/resolv.conf?

    6) Are you sure the DHCP server does not assign IP addresses in a range
    that might include the UW server's address?

    7) Try using a crossover cable to directly connect a PC and the server's
    NIC together. If Telnet then works, you have routing/firewall problems
    in your network.

    8) What do you see in the syslog after an attempt to telnet?

    9) Any chance telnet had been commented out of the services file?
