In reply to DMZ.???
Actually the Korean War is where the phrase comes from.
When you use a DSL modem, typicall all of the computers on the LAN side (your home or office) are protected via various security measures. Anyone from the outside can only see the modem.
However, a computer in the DMZ is connected to the modem, but it is not protected by any of the security measures enacted by the modem (hence the term DMZ).
When you use dial-up, your computer is basically left to fend for itself and use software protection like Windows Firewall, etc. So likewise, a computer in the DMZ would also have to rely on Windows firewall, which just so happens to also know about NetMeeting and will probably let it operate with no fuss.
So what I think you need to do is the following:
1) Check your DSL modem to see if it is handing out IP addresses automatically on your network (called DHCP). If so, it should show what range it is using. For example, the modem may be automatically assigning IP addresses in the range 192.168.1.100 to 192.168.1.150.
2) If this is the case, assign your computer a static address on the same subnet, but outside of the range that the modem is using for automatic addresses. Using my previous example, the last number could be between 2 and 99 (the modem is probably using “1”) or between 151 and 255 (255 is the highest number).
3) Now in the modem setup, find the DMZ setting and put in the static number that you gave to your computer (something like 192.168.1.25).
4) Now when your DSL modem connects you to the internet, you are not standing behind any of the modem’s security features and everything should work just as if you used dial up. But remember, only Windows firewall stands between you and the cold, cruel world.
Hope this helps.
