Website resolving differently on two different computer

[GodlessAstronomer]

I'm sitting at my desk with my desktop computer and a laptop. The desktop is connected with an ethernet cable to a router which is wired to a cable modem. The laptop shares the desktop's internet connection through a wireless ad hoc connection (the desktop has a USB Wifi dongle).

I'm visiting this photo printing website, http://www.digitalmax.co.nz
On the desktop it is resolving perfectly normally. On the laptop I am getting a site from a different company that says they are performing a database upgrade. I have ctrl-f5'd on both computers. What could possibly be causing this? Screenshots below.

Website on desktop computer (normal):

Website on laptop:

The desktop is running XP SP2 and the laptop is running Vista Home Premium SP1, both using Firefox 3.

A couple of things. The site could be load balanced across and one machine hit a down server (via dns round robin)

It could be adware/spyware/host file changes on the laptop (since the desktop seems fine)

If you ping the address from both machines, what do you get?

Ping from desktop:
Reply from 123.100.119.101: bytes=32 time=24ms TTL=57

Ping from laptop
Reply from 202.174.112.12: bytes=32 time=42ms TTL=120

I doubt that there is spyware on the laptop because it's only a week old and the first thing I did when I got it was install AVG and all of the updates and I have been super careful with it.

Edit - I also did a tracert on both computers. Results:

Well they are clearly resolving differently, why I dont know. Check your host file, the laptop could have been shipped with some adware (shopper supported type stuff) which is causing this. Most are browser plugins, strange your seeing this from ping....

Are you certain the laptop is connecting to your own wireless router and not someone else's system? (i.e. is martin.mshome.net your router?) I ask because the laptop got a reply from that router on the first hop of the TRACERT, but your desktop did not get a reply from the router it is connected to.

If the laptop is connecting to someone else's router, you might be getting bad DNS server info or incorrect name resolution results from that router.

Use the command line nslookup instead of just a ping. This utility queries your DNS servers specifically.

It's completely normal to get different and multiple records back. There's a windows DNS resolver vulnerability (poisoning) going and that may be what you're running into. I won't go into details on the vulnerability but that should give you enough to google.

The "good" news is that, at least, both IP addresses are located in New Zealand, and not in China or Russia. The "101" address is in Aukland, and the other is in Canterbury.
