Not quite sure what you're getting at... but if you're running into problems connecting to sites, the first couple of steps for troubleshooting is determining if you have (1) a DNS resolution issue or (2) a routing issue to the destination site.
nslookup is the Windows command-line utility to see if you can even resolve the target hostname.
Tracert will trace the route to the destination host.
Check both to see if there's a possible issue.
