    Rogers temporary disable my Cable Modem service, and the night shift has no idea about this and he suggest I call their network security tomorrow morning. is there any people could help me understand in which scenario they would block my Cable Modem service. thanks a lot!
    and I am running WIN2000 server, with DNS, DHCP,NAT services enabled, and open my FTP service as well to exchange some information with my friends via network.

      According to Cisco solution (CIscoVXR 7346, CNR).If you used NAT and just one CPE connect to Modem, they can not find there are other PCs behind the server. They should only get to know one CPE equipment (namely, your PC server) behind the modem.But if they use DHCP service and you config IP by yourself, they should get to know that.

        yes, I just have one CPE connect to cable modem, while the other PCs are connected to my second NIC and go through Internet via NAT, basically I don't think Roger could detect there are any hosts are behind my host, my concern is whether they allow me to run MS server, DNS, DHCP, NAP internally, and sometimes open FTP externally. thanks.

      Rogers does not limit your online PC number, only that they won't support you for solutions and problems.

      Check all of the following: (sorry if you've already known that, just try to help):

      1. have you changed your hostname? if so, change it back.
      2. have you been using static ip (altho the dynamic one doesn't change often), if so change it to dhcp to see if there's any difference.
      3. have you changed your nic? (which changes the MAC address) if so recycle your modem power
      4. have you enabled your port 25 or 110? if so disable them whenever possible, there're reported people using other's smtp to spam.
      5. disable all the services (at least on the first nic, not sure win2k can do that). you only need sshd for remote access
      6. if none of the above works, the only way is to first recycle your modem power and then reboot.
      7. if indeed you've disabled, you have done nothing wrong.
