The error youare getting reffers to your DNS server settings.
To se if this
Try going to network in your controle panel from there setect the TCP/IP -> (something about AOL) click the DNS configuration tab at the top. make sure that DNS is enabled. If not enable it and set host to (anything you want) domain to aol.com and lastley DNS server search order to 205.188.157.232 and 152.163.159.232 (these are AOL's DNS servers that I found on the web they might not be corect).
To alaberateon the last answer:
AOL has a known bug that most ISP's have seen. After the AOL install is complete the TCP/IP stack (your network protocall for the internet) becomes corupt. A mothed of testing is go to start / run type "command".
Then at the dos prompt type "ping 127.0.0.1". If you get request timed out then AOL has struck again.
To fix this: Try removing all AOL through the add/remove in your controle panel. After that reboot the computer. Then select network in the controle panel. From there remove all references to TCP/IP on your configuration menu. then got add / protcall / microsoft / TCP/IP. Then reinstall netzero. This will fix the TCP/IP problem if it exists.
