The proxy server isn't responding error message when using Internet Explorer 11

Hello and Good Afternoon Everyone,

              I wish to help my supervisor who is also a good friend with what appears to be a browser issue.  Whenever he attempts to get onto the internet using Internet Explorer 11, he gets the following error message:  The proxy server isn't responding.  The suggestions he gets to correct the problem is as follows:  1.  Check proxy settings 127.0.0.1:13081 , 2. Make sure firewall isn't blocking web., 3.  Check LAN settings, and 4. Ask a system administrator for help.  Interestingly, all other computers with the wireless connections are working just fine.   He also remembers receiving a message indicating the computer is correctly configured but the DNS server is not responding.  
The problem is with the main computer with the hard wired or ethernet connection to the Comcast receiver.  

              With respect to a possible cause, he said he only noticed the problem after using Malwarebytes.  Personally,  I can not see how this program could have caused the issue because I have used Malwarebytes several times in the past and without problems.  Just from the sound of things, I believe there is an invalid browser setting.  Of course, I am speculating and could be wrong here.  

                Just in case it is needed, the operating system is Windows 7 in case any changes need to be made within the operating system as opposed to the browser.  

               In closing, thanks so much in advance for any attention and suggestions given to this question.  I will look forward to reviewing all feedback given.  

              George

This sounds like a generic network issue not the browser. Run cmd. ping www.dslreports.com. Or just try another browser if you believe that one is misconfigured.

If he doesn't have connectivity then you need to go through basic networking troubleshooting.

One other thing to check is if he rebooted in safe mode without networking in order to clean his system and then never rebooted normally after that. It's a common thing to suggest to someone cleaning up a compromised system.

Hello and Good Evening

              Thank you for your suggestions.  After reviewing the information, I do have some followup questions.  First, could you provide a direct download link for an alternative browser, such as Google Chrome or Mozilla Firefox to try in order to help rule out the browser being the culprit?  Secondly, if the alternative browser does work, what would be the necessary steps for getting IE working again?  Is there a way of resetting IE back to its original default settings within Tools of Internet Options?  And, if all of this fails, what are the actual steps for basic networking troubleshooting?  I am somewhat familiar with the ipconfig and ping commands from past troubleshooting sessions.  At any rate, perhaps there is an article which can be printed out which goes through the necessary steps.

                In closing, I apologize for the followup questions.  I just want to make sure I am on the same page with you with respect to your suggestions.

                Thank you

Did you get your follow up questions answered in http://www.experts-exchange.com/Software/Internet_Email/Web_Browsers/Q_28415424.html ?

Sorry I didn't respond sooner, I was busy with site maintenance :)

The ipconfig and ping commands are a good place to start. One thing of interest is that wireless connections to the same router are working and wired ones are not. Does he have another device he can connect via ethernet and see if it's a generic problem? What kind of router is he using, is it perhaps a cable service providers leased one?

I looked and didn't find an article on generic windows trouble shooting. Seems like a very good idea for someone to write one.

Hello and Good Evening

               No problem with the slight delay in responding back.  I often have difficulty myself staying active like I should because of working 2 jobs.  At any rate, let me move onto responding to your questions.  First, my friend will be trying out  the suggestions given within the link of http://www.experts-exchange.com/Software/Internet_Email/Web_Browsers/Q_28415424.html this weekend.  As such, it will probably be Monday morning before I know the outcome of his efforts.  With respect to your second question, the modem box or receiver was supplied by Comcast which regulates his wired and wireless connections, cable, and phone too if I am not mistaken.  He did mention to me today that he contacted Comcast last night.  The tech he spoke to  adviced him to power off the receiver, wait about 45 to 60 seconds, and power it back on to see if the problem still existed.  Unfortunately, the error message of unable to locate proxy server was still present.  The Comcast technician thinks the box itself might need to be replaced.  Given this new information, I believe the people at Comcast think this is a connection problem and not a browser problem.  At this point, there is not any confirmed diagnois of the problem.  

               I will keep you posted on the progress of everything.  In the meantime, if you should have any further suggestions you would like to share, I am always open to them.  

               Thanks again.

Hello and Good Evening,

               I am very pleased to say this issue is now resolved.  The steps outlined within the link of http://answers.microsoft.com/en-us/ie/forum/ie10-windows_7/proxy-server-not-responding/93c96292-6940-4c2a-bd22-885c186f785c posted by stpmt11 from a recent post was exactly what was needed.  To make a long story short on this one, the proxy server was turned on or enabled within the Internet Explorer browser when it should had been disabled.  

               While the original concern posted is now resolved, I am faced with a somewhat confusing dilemma at this time with respect to the proper closure of this post.  Even though stpmt11 did provide the solution through the supplied link above,  his response was not given within this post which brings me to a question.  How should I handle the closure of this question in accordance to the policy of Experts Exchange?  

                In closing, I want to thank you Mr. Kehler for your suggestions.  You certainly kept the doors of troubleshooting this issue open to me by sharing your thoughts.  As such, I want to make sure you get some credit out of whatever final decision is made by an EE moderator as a gesture of fairness and recognition.  

                If you will, let me know what needs to be done on this matter because I am not sure what the next step of the process should be.  I just want to do what is fair and right on this matter.

               Thank you

               George

Since the real solution was found in the other question, I think you can go ahead and close this one accepting your own last comment, that way anyone who runs into this issue in the future will find the actual solution if they find this question. Glad you got your answer! I value the points, but I value the true solution more :)
