Can't Access Certain Websites

Recommended Posts

Hey Joe,

 

How are you connected to the Internet?

What browser are you using?

When did this all start happening?

Has anything on your system changed recently?

Can you get to the same sites in Opera?

 

Try deleting the browser cache (IE):

  • Select Tools|Internet Options from the main menu
  • On the "General" tab, click the Delete Files button
  • Check "Delete all offline content" and click OK
Also, go to Start|Run, type cmd and press Enter. Enter the following commands, one at a time:

ipconfig /flushdns

ipconfig /registerdns

 

The following webpage also offers some possible help:

Regards,

I connect by cable modem. This started a couple of months ago. I use IE6, Firefox, and Opera. Same problem all the way around. It's just a few sites. Nothing changed recently, that I know of. I'm running Win98SE. Did the cache thing and the dns thing, rebooted the modems and PC, still no good.

Check your hosts file. Go to C:\Windows (or equivalent) and open the "hosts" file with notepad. Make sure that the file looks something like the following (at least make sure it only has the localhost entry):

# Copyright (c) 1993-1999 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
#	  102.54.94.97	 rhino.acme.com		  # source server
#	   38.25.63.10	 x.acme.com			  # x client host

127.0.0.1	   localhost

You could try to re-register some of the dll files associated with your browser. This fix is generally for an inability to access secure sites - but sometimes it works when random sites won't work.

 

http://blogs.guardian.co.uk/askjack/2006/0...ecure_site.html

 

1. Ensure that all Internet Explorer windows are closed before continuing.

2. Click onto the "Start" button in the taskbar and then select "Run"

3. In the Run prompt type command and then click the "OK" button.

4. In the black command window that appears type each of the following lines (including spaces) and press the "Enter" key on your keyboard at the end of each line. Each file that gets reset should provide the message "DllRegisterServer in FileName succeeded". Confirm this message before typing the next line of text.

 

 

regsvr32 softpub.dll

regsvr32 wintrust.dll

regsvr32 initpki.dll

regsvr32 dssenh.dll

regsvr32 rsaenh.dll

regsvr32 gpkcsp.dll

regsvr32 sccbase.dll

regsvr32 slbcsp.dll

regsvr32 cryptdlg.dll

 

5. Once all 9 files have been reset type the word exit (and then press the "Enter" key on your keyboard) to close the command prompt.

6. Re-open Internet Explorer

 

It should work

@akokes: You might want to read the whole thread, Joe said the issue isn't isolated to IE.

 

@Joe: The fix that akokes suggested is only applicable when IE is problematic, but you have said you have the same problems regardless of browser. The fix won't work for you in this case. Have you tried the suggestion from my last post? Please post the results of the test.

 

Thanks,

Contact your ISP if you haven't already, it may be a problem on their end.

 

Not a problem on their end. This happened once before. When I had my hard drive replaced and the computer was "fresh" again, it worked fine for a while, so it has to be something with my PC.

Are you using a Belkin router with "Black List Defense"?

 

No. Zyxel. And everything worked fine for a while. Can't pinpoint when it went bad for some sites, as I only go to those sites every couple of months. :pullhair:
