Error message: no server detected

Hewlett-packard / Pavilion a400n
April 18, 2009 at 06:08:29
Specs: Windows XP
Starting three days ago, I began getting this error message when I attempted to access websites in my bookmarks, which I use daily:
Address Not Found

Firefox can't find the server at

The browser could not find the host server for the provided address.

I spent two hours troubleshooting both the questions with the error message and every other possible solution/suggestion from Microsoft, Windows etc. and even swept the computer for viruses once again. This is happening with two sites every time I try to access them, sites that I have connected to hundreds of times.

System info:
HP computer, XP OS
Clearwire internet access
Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv: Gecko/2008070208 Firefox/3.0.1

Has anyone else experienced this? Know to how solve it? I asked my computer guru; he said one other person has reported similar problem this week

Thanks, Noel (driving me crazy)

Clear the browser cache. You can do that easily by using Ccleaner slim. get it at the link below.

I just cleared the cache. Still get the same identical error message

How did you clear things? The index.dat file can't be removed using normal methods. That file may be the problem. Ccleaner can empty it.

Forgot to ask if you can reach the site by typing the URL instead of using the link in Bookmarks?

Thank you.
1) I followed your link, updated my CCleaner via Major Geeks, then cleared the cache for Firefox via CClearner

2) No, I tried both bookmarks and typing url into Firefox address line, dozens of times, same result "can't find server"

3) I still have Explorer 7 in system, rarely used. Tried to use it as alternate, but it will not open the site(s), flips me automatically over to Firefox, where I get the error message

Not being able to independently use IE7 is odd. I have both FF3 & IE7 and can use them independently. I have been having a problem lately with FF3 though. I seem to constantly apply Ccleaner to get online or I get a whit box an no internet.

I have run various scans and all come back clean.

Can you restore your WinXP back four days using system restore?

Thank you. I already tried system restore. Restored back to April 1 just to be safe. Did not solve the problem.

The fact that IE 7 is not independent of Firefox puzzled me, too. I have not used that program for months. As I indicated, this problem that is topic of thread just started last week. My system has been molasses slow, however, for months, especially on reboot and startup. Sometimes taking five minutes. No solution for any of the fixes I have tried as a total amateur

Also, please note. Besides entering the complete url/file extension in the address box, I also try to access simply, and still get the "can't find the server" message. As I said, I have tried many fixes and solutions. On the first day, after a dozen or more tries, the full address finally opened. I worked in the file, then closed, and it would not open again. This repeated, temporarily open, then close. But now, even with dozens of tries, the file will not open at all, get the same error message every time.

Is that the only site you are having trouble with?

No, also

I have checked with other people who frequent those sites. They all reported back yesterday that they have not had the same problem (at either site) and all are using Windows XP, either firefox or IE

Both sites appear to be run be Are you sure you haven't been banned or are not being blocked by the sites?

Can you access them from other computers?

That was the first thing I checked. I have been logging onto these EZBoard/Yuku sites for more than ten years. I have not been banned. I checked with the administrator of both boards. If I had been banned, I would have received a pop-up message to that effect. As I noted, on one day, I was able to access both of the sites off and on, post on them and receive messages onto them until I closed the site. Then I was not able to re-enter them.

But I will check again just to make sure. That was my first question: why those two sites? Thank you for the suggestion. But I am assuming until told otherwise that this is not the answer.

Try making an exception to any blocking of cookies, etc. In your browsers. Both are updated continuously and sometimes that changes the security settings.

Thank you for the suggestion re: cookies. But even though I have used computers for 20 years, I am still a virgin/novice. Could you please explain, step-by-step, what you mean re: blocking cookies, so that I do not foul it up or go on another wild goose chase?

In your FF3 browser go to Tools> Options to find all the settings. Under content, for instance you can accept cookies from those sites even if blocking others.

You might email the administrator of those sites for help on settings.

Who is your ISP? Some are now blocking sites they think are peer to peer sites. I don't know what your sites are about. Contacting your ISP may shed some light on things too.

If you KNOW for sure this started exactly three days ago you could also look in Add/ remove programs in Control Panel to see if any updates were fed to your computer on that day. If there were then Google to see what those updates were for.

You need to check the box in add/remove programs to show updates.

Okay, I will follow your advice re: cookies and FF3. Negative on updates on these days in my control panel info. As I indicated above, my ISP is Clearwire. I just emailed to them but I fail to see how or why they would do so, especially without some kind of legal notice to cover their butts. I'll report back when I have finished the rest. And I also emailed both the site administrators just in case, to determine if I was banned and how that could have been done without informing me. One already answered and assured me that is not the answer. So, how could the other admin have done it? Sigh. But I asked anyway. I want to solve this.
Thanks for your time

Your ISP can do pretty much anything they want to do. That is the sad truth. I am not saying your ISP is the issue. I am pointing out possible explanations. Your security settings may be set too high.

BTW, posting your email in the open like you did is an invitation to get more spam.

I am not sure if blocking cookies would yeild that message but is sending out a cookie when you go there. Allow that cookie in the settings like I described above.

Thank you again. Yes, I am about to apply that suggestion re: the cookies. And sigh, yes, I know about the email exposure, but that is the least of my frustrations at the moment.

In addition, I do not hold out too much hope for the cookie solution because how would that have affected the IE7, which automatically flips me to Firefox, when I try to access there either of the problem sites? I checked and sure enough, I did access IE7 briefly last week. And at that time, it did not flip me over to Firefox. So, how could these two problems -- no server; and IE7 flipover -- have combined? At random?

Re: your suggestion--
"Your security settings may be set too high. "
How so? And I have never changed my security settings in years. So, how would that have changed without my input, suddenly, three days ago?

I told you how. Both browsers update by default whenever they have new files. IE, at least, may reset the security to higher settings. Not sure about FF3.

Problem solved. I could not contact Yuku directly, obviously, because firefox told me that did not exist in any form. But finally I found a Yuku member, second-hand who passed on a rumor that Yuku had posted a website addressing the problem. So I tracked down someone who accessed the website. Sure enough, Yuku blames the snafu on a group of (list not actually posted yet) ISPs that all combined on one day to block any one of Yuku's and EZBoard's hundreds of forums.

So, I went to the source and confronted Clearwire, my ISP, about it. The perky chat rep insisted she was ignorant of any such problem and then proved to be ignorant of computers in general. She makes me look like an IT pro. She then referred me to Clearwire Service Support and miraculously that office was open to phone calls today.

The service rep was quite surprised when I explained in 50 words or less what the problem was. I restrained myself, keeping in mind that it wasn't this guy's fault. He launched step one, trying to access either of the sites from which I was blocked, or the root sites of or And was shocked to find that even using a non-Clearwire ISP, Firefox still told him that none of the four sites existed. He put his thinking cap on and surmised a hypothesis to study: could someone at Yuku have been performing maintenance or "cleaning up" connections and inserted an incorrect code or a bug into program that only affected x percent of users? So we tested it. He went back to Computer 101 and guided me through the Control Panel and the LAN connection codes. He gave me what is effectively an override code that ignores any block that an ISP has put on for any reason, or any connection code from a system that Yuku might use. I inserted the four-number code in two places, went back to Firefox and both sites immediately opened up.

Meanwhile, Yuku is blaming Clearwire and other ISPs. And Clearwire doesn't know who to blame.

I tend to doubt that a whole list of ISPs all colluded on the same day to block all the Yuku sites, unbeknownst to each other, and without telling any of their users. Such a conspiracy theory makes about as much sense as Jack Ruby taking his poodle dog along as he supposedly assassinated Oswald, or the whole Grassy Knoll story.

Thank you, OThehill, if you were here, I'd buy you a drink. I am very impressed that you hung in there and spent all that time helping me. scores again, the second time in three years for me. Can I get an amen?

I thought that might be the problem. There has been some of that sort of behavior going around.

It is too bad that your ISP had to lie about it though.

If I may...

A lot of ISP's have started a group blocking of suspected spyware/malware and other sites that have been reported to have been used to download viruses and the lot or the sites are no longer available. There is several Master Lists that are used to go by. These lists are created by third party vendors and not the ISP's them selves. The lists are suppose to be verified but from time to time a website has been known to be included on the list that was neither and never had been.

The suspect on this is webBots that are used to visit sites. If the site is not available for any reason it is reported to be a bad site. Another Bot is sent to verify and if it reports that it is also down then the site is blocked as no longer available.

In most cases the webBots are blocked from the site because of suspected spying themselves as more and more websites are blocking certain types of these types of intruders as they are also used to Spam and insert malicious software....Kind of a catch 22 situation, as bots are used to supply information back to search engines as well.

This is taken from

squidGuard Blacklist

While it is for private domains and networks it gives you an insight as to how it is done and then the list is collated and then used to effectively block these sites that are on it!

The squidGuard Blacklist is a public-domain collection of site lists which can be used with the Squid proxy (under UNIX) and now also with Novell BorderManager. This list is generated by a software "robot" which searches the Internet looking for URLs which fit into one of squidGuard's predefined categories.

The categories of sites currently maintained within the squidGuard Blacklist are:












warez (pirated and illegally "cracked" software)

As you can see just one poster infringing upon a website certain information can get the website banned from use through this type of blacklisting software. If a single search bot finds the post then the site is blacklisted...the problem here is that in doing so the actual use of the blacklist may not be used for days or even weeks that time the original post that was registered has been archived and it is hard to find by the webmater so as to argue that his site does not perform what it is accused of.
