100% Packet Loss | DNS Resolves | New Domain

[hambone]

Okay, so I'm frustrated with these damn Citrix connected machines in the honours lab at Stellenbosch Uni. I recently registered www.sunconsults.co.za with domaincheap and have my NS setup correctly. The computer to my left, runs XP and is not connected to Citrix, the computer I am on right now runs off Citrix.

So, to the left the site loads just fine. Right in front of me I cannot ping the aforementioned website. Does anyone have an explination why the DNS is resolving but there is no throughput on the Citrix machines (or would care to hazard a guess)?

Have I got the ns configured incorrectly? Or is there a routing issue that terminates somewhere in Texas? Any suggestion ye network admins?

Your DNS is setup correctly since it is resolving the name to the IP - see my example query below.

You problem is definitely routing as it dies along the path. Somewhere in (what might be) Texas, as you say.

Ta Is it possible that since the domain was only recently registered that it wouldn't have the routes in place*? Is this my host's issue or should I contact SysAdmin at the uni?

*Please excuse my ignorance in such things...
