I am at my ropes end. I have a reseller hosting account on a Unix/linux like server. We recently change to a new server. Different IP address. DNS was updated. As far as I can tell all records set up correctly. The problem is I can ping the IP, not the domain. (using cmd) Unless I navigate to the url in a browser. Then for a while I can resolve. Until the browser or tab is close. Then can not be resolved. I can ping google, ebay, any other domain. Just not the Hosting and my reseller host. I can ping all A records if I use a Internet network tool. Like Traceroute, Ping, Domain Name Server (DNS) Lookup, WHOIS . On one hand I think it my home network, or ISP. Hughesnet (uses browser proxy). The other hand I thinks its dns. Its been a week or better. I can go to the url in the browsers no problem. (IE8, Opera) Mail client can not resolve mail server unless I navigate to mail.litesitehost.com. Then the record works until a shut the tab down. I can use the ip as a server just fine, every time. Would someone ping, or nslookup; mail.litesitehost.com for me. If it resolves then its my network or machine. I just can understand this one. I flusheddns. stop/start dns cache. windows 7 all updates.
