GoDaddy Server Help With Problem Related to Zones/DNS/Nodes

Hey All, I have a Dedicated Server through GoDaddy with WHM/CPanel. I'm having an intermittent problem. Where some and/or all websites go down. Here is an example I had about an hour and a half ago: I could access SITEA through the domain, which is the main hosting domain, a friend could not, yet we could both access the website via the IP address. Also, I could NOT access SITEB, which is a sub account on the same server, my friend could, but we could both access the site through the IP address. At the same time, I couldn't access either site through an online proxy using the domains. So I've talked to both sides of GoDaddy support, for the server it's self managed, so they are little help, and on the domain side, the analyst suggested it was a problem server side and to look at the zones and nodes. They also noted this MIGHT be the problem "Non primary ip addresses are being allowed to relay. Setup prmary ip to be the one that should be relaying and update the zone files. " So what I need is someone that can walk me through checking my server. Payment via GAF escrow. Must be available now, via MSN or Skype chat. Budget: 30
