All computers in network cannot access certain sites

[Guest]

Our company recently moved and switched DSL providers, we are now on SBC.
Since the move, we cannot access some of our sites that we need to access
(aspx sites or like). Also we found out that we cannot access Yahoo! Mail or
Hotmail. It just timesout and goes to page cannot be displayed. It worked
before on the former provider without a problem. I ran spyware
(ad-aware,spybot,hijackthis in safemode), cleared cache, deleted temp files,
deleted hosts, ran regsvr, changed the time. I am out of ideas, does anyone
have an idea on what this problem could be?

I tried this too, but there is not dice on these.

Hi,
First try a complete shutdown (power off) of the system. Shutdown all
computers, modem, router, hubs, etc for 5 minutes.

Then, how many machines? Which OS? Same OS on all machines?
