Help! Network configuration

[red45]

I need help with network configuration. I have got xp, Trek Earth and Trek Lens working very good, same as all others wwws. Trek Nature doesn't work :-( If I try to connect to TN I have message 'Server not found or DNS error'. Same thing if I try to write IP adress in Explorer instead of www.treknature.com. I didn't use my home computer for some time and think this problem is related with TN transfer to the new server. Computer in my work connects to TN without problems.
Please help!
Greg.

It's possible that the TN server (or your route to it) was down when you tried to connect to it, it's also possible that there's an obsolete DNS record somewhere. What happens when you try and ping www.treknature.com?

I'm finding it OK on:
<a href="http://216.22.50.180/" target="_blank">http://216.22.50.180/</a>

I've solved the problem. It was fault of DNS caching in Outpost Firewall. Old IP adres was connected with to TN.
Thanks for your words,
Greg.
