[OPLINTECH] Internet problems:

[Dan Will]

To touch on something Chad said:
<snip>
If the problem is only affecting the browser, then it sounds like you 
need to focus on things that would cause the browser to not work. The 
problem affects multiple machines, so the problem is more likely to be 
centralized. If you have a proxy or caching server that proxies and/or 
caches HTTP traffic, that would be a good place to check. It would only 
affect HTTP traffic. You could also verify that DNS is resolving 
correctly when the problem occurs. If the URL can't be resolved to an
IP 
address, it could act as you described.
</snip>

An easy way to check this is:
On an effected machine. 
Open a command prompt and type:

ping google.com

This should (if DNS is working correctly) return a response.

If not type:

ping 72.14.207.99

This should return a response as well. This just verifies that your
network is connected to the net.
If the first times out, you definitely have a DNS problem. If both time
out then you have a network problem.
