Hello I'm an online college professor and I can't access my university website although all other sites come through ok.

I use a Firefox browser on XP. Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.10) Gecko/2009042316 Firefox/3.0.10 I have a broad band connection. I use Windows XP, service pack 3.

I've contacted the tech support at the university and they say that the site is UP, and they have no problems with it. But when i try to access it, through either my Firefox or IE browser, I get this:

Address Not Found

Firefox can't find the server at mentors.ncu.edu.

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

* Did you make a mistake when typing the domain? (e.g. "ww.mozilla.org" instead of "www.mozilla.org")
* Are you certain this domain address exists? Its registration may have expired.
* Are you unable to browse other sites? Check your network connection and DNS server settings.
* Is your computer or network protected by a firewall or proxy? Incorrect settings can interfere with Web browsing.

Try again

At the bottom left of the page is a box that says: done. At first, at the bottom left the address of the site shows, then, when I get the above remark, I also get the "done" message there.

The university site for teachers is password protected but not even the entry page comes up. The tech people even gave me a "direct link" but that didn't work. I also tried going to the history section and clicking on a previous history entry for the site, but the same thing comes up.

I use AVG anti virus and did a scan and everything was ok.

Any help you can give me would be appreciated.

In peace

Dr. D'Elia

Can you access http://63.149.31.34

Drd · « **Reply #2 on:** June 11, 2009, 06:06:44 AM »

Broni: When I try to access what you gave me, it takes a long time, and then I get the URL at the top, a blank page, and "done" in the bottom left.

What's going on here? Why is only the university address, and now this one, inaccessible for me. I can go everywhere else except to work!

Thanks for your help.

Broni: I've found out something: When I try to connect to my university site through my ADSL broadband I get the error message. But when I use my old dial-up connection I do get through. I've been using the ADSL for over a month now with no problems. What could be causing this to suddenly not be able to get through to the university site?
Thanks
Dr. D.

Three things to try:
1. I made a mistake, putting backslashes instead forward slashes in the above address. So it's : http://63.149.31.34
2. If you use router, try to connect straight to modem, and see, if you have same problem.
3. Try Safe Mode with Networking.

Broni: When I use that number thing that you sent, I get this message:

Secure Connection Failed

63.149.31.34 uses an invalid security certificate.

The certificate is only valid for the following names:
*.ncu.edu , ncu.edu

(Error code: ssl_error_bad_cert_domain)

* This could be a problem with the server's configuration, or it could be someone trying to impersonate the server.

* If you have connected to this server successfully in the past, the error may be temporary, and you can try again later.

Or you can add an e

Make sure, your computer date is correct.

Drd · « **Reply #7 on:** June 11, 2009, 09:23:54 PM »

And how would I do that? I went to the little time box in the corner and clicked on that and it showed the correct date.

Also, please note my previous post where I say that my broadband connection is not connecting to the site, but I found out that an old dial-up connection I have does connect. So does this mean anything to you?

By the way, on the bottom of the error message for the .63..... that you sent, there was a place to "make an exception". So I'm trying to tell the computer to make an exception. It has done and brought up a site that looks similar to, but not identical to the one I usually use. Can I trust this to be authentic? Should I try and deal with that site?

Thanks

Did you try #2, and #3 from my reply #4?

Drd · « **Reply #9 on:** June 11, 2009, 09:30:31 PM »

Broni: I don't know what you mean by a router. Sorry.

And, where do I do the "Safe Mode with Networking"? I'm using the firefox browser.

Thanks

Restart computer, and keep tapping F8 key until menu appears:

Select SECOND option.

Drd · « **Reply #11 on:** June 11, 2009, 10:13:19 PM »

Broni: F8 doesn't do anything for my computer. Should I try a different key?

Thanks

Dr.D

Broni · « **Reply #12 on:** June 11, 2009, 10:25:07 PM »

No. All computers use F8 key.
What brand, and model is it?
I assume, you're TAPPING, not PRESSING F8 key??

Drd · « **Reply #13 on:** June 11, 2009, 10:35:17 PM »

Hello: I don't know about the brand and model. It's a composite I think.

When I tap and tap the F8 key, I get a note that syas Please install Express Recovery 2 for gigabyte CD title. Then, the computer froze. So I shut off and started it again. This time I pushed the f12 button and then it froze again. So I don't think I should fool around with those buttons on start up. I'm afraid I'll ruin something.

Would you like to try taking access of the computer; or do you have anything else you can suggest?

Thank you
DrD

Broni · « **Reply #14 on:** June 11, 2009, 10:37:13 PM »

What about my suggestion #2?

Drd · « **Reply #15 on:** June 11, 2009, 10:42:01 PM »

I'm sorry that I don't know what you mean by saying that "If I use router connect directly through modem". I don't know what a router is or if I use one or not. Sorry to be so uninformed.

DrD

Broni · « **Reply #16 on:** June 11, 2009, 10:46:31 PM »

Do you have only 1 computer connected to the ADSL router?

Drd · « **Reply #17 on:** June 11, 2009, 10:49:55 PM »

Oh, by router do you mean the little black box with the yellow lights on the front? Yes, there is just one computer connected to this.

And, now that I think I understand you, as I said, my dial-up, which goes through a modem, does make the connection to the site.

DrD

Broni · « **Reply #18 on:** June 11, 2009, 10:53:04 PM »

Turn off computer, disconnect your modem from the power source for 1 minute.
Power the modem back on. Restart computer.

Drd · « **Reply #19 on:** June 11, 2009, 11:27:33 PM »

I did that but nothing changed. Still the same message.

What next?

DrD

Broni · « **Reply #20 on:** June 11, 2009, 11:33:53 PM »

Unfortunately, I don't have any fresh ideas for now

Drd · « **Reply #21 on:** June 11, 2009, 11:49:16 PM »

OK. t hanks for all your help. I'll try to contact the ADSL people and see what they can come up with!

In peace

Bruno: I just want you to know that the ADSL people resolved the problem. It took a couple of days but now I am able to connect to the site through my ADSL once again. Thanks for your patience and help.

Dr. D

I'm glad, you're back in business

Bruno...

Broni · « **Reply #25 on:** June 16, 2009, 05:07:57 PM »

Oh, I got used to it...

Drd · « **Reply #26 on:** June 16, 2009, 10:25:34 PM »

Sorry: Make that Broni, MR. Broni in fact. I'm kind of old
