Okay, I've finally had it. I am vowing never to use Network Solutions again. I've put up with their crap for years because they made it easy to delegate management of their domains, but now I am freaking irate because of their hideous incompetence.
Apparently, when you transfer a domain to networksolutions.com they feel free to host their own web page on your domain for you. That's right, I just transferred two of our customer's domains to them, and what shows up today? A network solutions logo with one of their idiotic domain parking pages. I went in and set the DNS to point to the right place using THEIR OWN management tool. I then did a dig directly on the DNS server assigned to me. Guess what? NO CHANGE. Four hours later, still no change -- their DNS servers are still reporting their own informercial site as being our website.
This, along with their DNS admin tool being trash (doesn't even support TXT records -- how do you do SPF records and the like without TXT records?), has finally convinced me to find someone else for a registrar -- Network Solutions is terrible.
