Check your current IP address. I don't know what it looks like in XP, but in Win98 you do a "winipcfg" command in the Run block; in Win2000 you do a "cmd" in the Run block to open a window, then run "ipconfig". This will display your current IP address. If it constantly changes with logins (dynamic), you're out of luck. If it stays constant til your ISP's server reboots, then it will work and the remaining step is to go to where your domain name is registered (register.com, for instance), and change the IP address that the domain points to. You should have a username and password already to log in and do this.
