Hi All,

 

Great resource everyone, thanks.  a few weeks ago my work computer got infected with the trojan.zaccess virus.  I basically followed the steps here:  http://forums.malwarebytes.org/index.php?showtopic=131741  

It got rid of the virus.  However, I noticed last week that I can no longer access this website:  https://oedci.uspto.gov/OEDCI/

 

That website is the roster of patent attorneys at the US Patent Office.  I can access everything else (so far) at uspto.gov, I can file patent applications online, search patents, etc.   I can also access other websites with the "https://" address.

 

I called the USPTO and the told me nothing wrong at their end.  I called at&t, and we went through all sorts of tests, and finally they just sent out a guy to replace my UVERSE modem/router, and still the same problem.   

 

So, now I am coming here to see if I did something to my computer when fixing the virus that will not let me access that particular USPTO page. 

 

I can access the website on my cell phone IF and only IF i turn off wifi and use the verizon cellular network.  If I use the wifi, i cannot access that website.  I can also access the website on my home computer using my home network.   Thanks in advance!

Just to make sure I understand...both the work computer AND your smartphone that uses the work WiFi have problems with the website, correct? If so, does the computer connect by WiFi or ethernet?

If both are having trouble when using your work network, then it tends to suggest that something is wrong with the network rather than the computer and phone.

Smax013, my work computer has a wired connection to my UVERSE modem/router at work.  My smart phone uses WIFI (wireless) to access the UVERSE router.  When the AT&T tech came over, he was able to get his apple tablet to work accessing that website using the same wifi network.  My computer is a PC and smartphone is an adroid (not apple).  By the way, when I access that website on my home computer using my home wifi, I am able to access that website, but i do get a window that pops up that says "only secured content is displayed".  That window seems to always pop up whenever I access that page, or links on that page (it is very irritating).  That leads me to think that maybe there is a security setting in the network that was changed that affects PC's, but maybe not apple products?

Does your Android phone work over WiFi when you are at home?

yes, my android uses WIFI at home.  And I can change my android to use the Verizon cellular system.  when I use my wifi at home, or use the Verizon Cellular system, my android can access the website.  When I change the cell phone to only use my work wifi, then my phone can no longer access the website.

See my posting at:  http://livingstingy.blogspot.com/2014/12/dns-resolver-issues-dnsprobefinishednxd.html

 

 

DNS.png

DNS servers resolve Domain Names to IP Addresses.  If they go wrong, you can't access some sites

 

What do you do if suddenly, some websites don't seem to want to load on your computer?   I have been having this trouble for a week now, and the websites are all for the United States Patent & Trademark Office. 
 
I called the USPTO electronic business center helpdesk, and they are usually on top of things.  They indicated a lot of people using AT&T or UVERSE were having trouble accessing the site.   They suggested that AT&T's DNS server was redirecting website requests improperly.
 
I called AT&T and they tried to help (three hours on the phone or in chat) but could not resolve the issue.  Sometimes "flushing" the DNS cache (c:ipconfig /flushdns) sometimes would help, as would clearing cookies.   But this only allowed access to some USPTO sites, and not all, and the next day, the problem would re-emerge.
 
The error message you get, depends on which browser you are using:
 
 
Explorer: This website cannot be displayed
 
Firefox: Server not found. Firefox can't find the server at www.xyz.com
 
Chrome: This webpage is not available. The server at www.xyz.com can't be found, because DNS lookup failed. DNS is the network service that translates a website's name to its Internet address. This error is most often caused by having no connection to the internet or a misconfigured network. It can also be caused by an unresponsive DNS server or a firewall preventing Google Chrome from accesing the network. Error code: DNS_PROBE_FINISHED_NXDOMAIN 
 
This latter error message (Chrome is more helpful than Firefox or Explorer in providing details) lead me to a Google Search which found some useful help.
 
 This site has some helpful information:
 
 
It seems like you are having DNS problems. First thing I would do is try clearing your DNS cache:
ipconfig /flushdns
If that does not help, then try changing your DNS servers temporarily to Google's (8.8.8.8 and 8.8.4.4) just to make sure that the DNS server that you are using is not having problems.

To do this on windows 7:
  1. Open Network and Sharing Center.
  2. Click "Change Adapter Settings".
  3. Find Network Connection that is used to connect to internet (either "Local Area Connection" or "Wireless Connection"), right-click on it and click Properties.
  4. Now in new windows select "Internet Protocol 4 (TCP/IPv4)" and click Properties button.
  5. In the new window click the checkbox for "Use the following DNS server addresses:"
  6. Type in 8.8.8.8 and 8.8.4.4
  7. Click Ok and close the rest of the windows.
After this is done, check your internet connection and if you can open pages.


Well, I tried this, and it works.  By using Google's DNS server instead of AT&T's, I can access the USPTO websites again.   Damn you Google, for being so helpful!   AT&T gets a "nice try" award, but their help desk people could not figure it out.
