Cannot Access a Specific Website on any Windows Workstations in our Domain

Posted on 2014-09-04

For some reason when trying to access a specific website www.sfgsa.org from any of our workstations or servers in our domain all browsers ( IE, Fire Fox and Google Chrome) just sit there and finally error out stating "verify or check to make sure the website is correct". I can access this via other servers not in our domain or from pretty much anywhere else.

I can ping, trace route and nslookup the above website with no issue's. I verified my firewall is not blocking the website. I'm wondering if somewhere in DNS I have some configuration blocking it. I verified my Forwarders for DNS servers are using my Internet Providers.

Does anyone have any more idea's or direct me for more information. Thanks  in Advance.

with nslookup, if you use an internal dns server to resolve the IP address, does it match if you resolve using a google dns server (8.8.8.8) ?

Check your firewall to make sure the site is not being blocked or add it to the trusted sites in Internet Explorer. Verify if you can ping the site to see if it's even making it passed your firewall. If it does check the compatibility and trust settings in Internet Explorer.

Seth, Yes it does resolve the IP address and match.

MHMAdmins I did add the website to the trusted sites and verified it pings pass the firewall. I even did the compatibility mode.

I checked my DNS Server Root Hint and only 1 root hint was outdate, so I updated that as well. I know it takes time to propagate.

I have a Diagnostics Task in my firewall to where I can run dns lookup, ping and nslookup and they all resolve correctly.

Is sfgsa.org the same name is your internal domain?

Do you run a centrally managed AV software with whitelisting? Could be an AV product blocking the website.

We have a SCCM 2012 Server with Microsoft System Center Endpoint Protection add on for the clients. This only pushes out virus signatures and allows us to manually run scans. We have it every morning when a user turns their computer on to update the virus signature and then on 1 day of week run a full scan.

I verified my firewall is not blocking this website. I still not able to access this website via my external IP address. I did see that address was blacklisted. That has now been removed. Still can't access it, however now that this is a Government website I'm trying to contact them to have me unblocked. I think this is the issue. I will update this when I find out.
