[thelist] Checking DNS of an ISP

[Gustavo Arizpe]

Hi, I have a customer who connot see his web site (hosted in a virtual 
hosting server which I resell) in his local network. Outside his local 
network the site loads quickly.

I believe the problem has to do with his ISP DNS or even his local 
network DNS, but I don't know how to prove that. How could he check 
this in Windows, i.e. how could he verify that his domain name is not 
misconfigured in his local network or his ISP's?

If he does traceroute all he gets is slight delays, but via http the 
site takes ages to load, so my guess is some local misconfiguration of 
DNS, either in his local network or his ISP.

Any suggestion will be appreciated.
