Have a domain with one computer, (XP Pro with IE7 fully patched), that can't resolve most .gov public web pages. It can resolve our own .gov page, but not most .gov public web pages like some Coast Gaurd pages.
On that same domain, I can go to another computer (XP pro, IE7 fully patched) and it displays just fine. What I am trying to say is my domain DNS servers appear just fine.
Check this out, here is the odd part:
On the problem child computer, if you type HTTPS://(gov_webpage).gov
it would load the web page. Or at least it use to. This worked for a while, and now doesn't.
On the other computers, these sites resolve just fine.
What the Heck??!!!
~Checked DNS cache, it looks good.
~Checked the host file>>not configured with anything but the loopback address.
~I can resolve these sites on another PC. So, DNS is good.
~I can even ping the web page and get the right IPaddress for DNS resolution back from DNS, but the remote site has ICMP turned off. So, no replies to any PC's
~I went into internet explorer and disabled, Unchecked the option "check for HTTPS" in trusted sites. That didn't work.
~I went into control pannel and disabled windows firewall, just out of curiosity I check firewall in services and found out it was still running. So, I disabled it in services as well.
~Most sites work just fine, on the problem child. Just not .GOV sites.
~I changed from Forwarders, to root hints and back to forwarders on my servers. No, change.
~only one machine is showing these problems.
~ I have not tried firefox yet.
~I added site to trusted sites
~NO errors in event logs.
Things to note:
~According to the user, this happened about a month ago. So, I am suspect to a PATCH or SP.
No,I am not smoking any wacky weed. Does anyone know of any settings that may knock down most .GOV web sites on one machine? I can't think of anything that would cause this.
