Hi, recently i switch to a new host. i bought 4 domains via Yahoo Domain (yy.com) and point their NS to my host's NS. i also switch one of my older domain (xx.com) NS from the old host to my new host's NS. I set up addon domain at the cpanel of my host. when i tried the next day, the change is successful. i had confirm this. but after 1 wk, when i tried yesterday, the domains point back to their previous NS. (e.g my older domain (xx.com) points back to my previous web host, those new domains (yy.com) points back to yahoo domain set up page.) pls help
