websites down - how to troubleshoot and diagnose

I need to know what utilities are out there to troubleshoot and diagnose reasons why a website says "The connection has timed out"

IIS7 running on Windows Server 2008.

We have 13 hosted sites that are down...all say the same thing.  IIS7 says the sites are running.  We can remote into the webserver itself so the server is up but the sites are down.

Hi,

I don't know if there are utilities for it but this is what I would do.

1. Is the sites working from the local server?
2. Is the sites working from the local network?
3. Check the DNS with host or nslookup, do you get the right IP from Googles DNS (8.8.8.8)
4. Check if you can access the web server from remote with the IP instead of the hostname.

By this you should be able to determine if the problem is in the IIS bindings, local software firewall, network firewall or DNS.

Can you browse the sites from within IIS 7?

Checked DNS to make sure it is reporting correctly?

Checked ipchicken.com to make sure your 1:1 NAT is behaving correctly, if applicable?

In desperation our help desk guy disabled Windows Firewall completely...and all the sites work now.

He just barely did this after I posted my question.


So........  I guess my question now is ....  what do we need to change / check   so that when we re-enable Windows Firewall, the sites do not go down again?

I guess we use PFSense for our firewall?

We may just leave Windows Firewall disabled for now....
