Some providers start replying with "helpful navigation assistants". If you are not on a DOMAIN or WORKGROUP and don't have control over the DNS server you are asking I'd give the provider a phone call and ask why they are mucking with DNS.

Also you are not giving us the information you get from DNS, dig is my tool of choice that can tell what exactly is going on looking at the DNS site of things...

May I suggest that these kinds of questions be directed at superuser.com - It seems more a "Desktop/Workstation Problem" than system administration...
