Unable to view web pages over our network yet other Internet traffic is unaffected

Hi,

We are experiencing a very frustrating problem at the moment and I hope that somebody knows the solution.  We have an office with 1 server, 5 PC's and 4 Macs.  None of us can view web pages in IE or Firefox.  However, the broadband connection is clearly working because email to our exchange box is not affected, and I can use terminal services to talk to the server from outside the office.  I can also pick up pop email.

Our virus software (NOD32) is not showing anything untoward.  Hijack this hasn't shown anything unexpected and I have changed the firewall, yet the problem has reappeared.  I have also double checked the DNS settings (as well as tried redirecting the DNS through another server) but this makes no difference.

Does anybody know of a virus or something similar that might cause this or have any other ideas?

baileytibbs,

Run this script to fix your connection
http://downloads.subratam.org/WinsockFix.zip

The script resets your winsock, TCP/IP stack, and HOSTS file.

Hi,
Thanks for this but the problem still remains after running the utility.

1. Do you have a firewall browser traffic?  Temporarily disable the firewall and see if you can access the website.

2. Clear your DNS cache.  Go to Start > Run and type CMD
and hit OK.
At the command prompt, type ipconfig /flushDNS
and hit OK.

3. Clear your cache.  Go to Tools > Internet Options > General tab.  Under Temporary Internet Files, click "Delete Files" button. Click OK.

4. If no joy, check if your PC is blocking the site.  Do a search for HOSTS file and open it with an editor like Notepad. Delete any line that has the blocked site in it.

HOSTS file is located in
Windows XP      =      C:\WINDOWS\SYSTEM32\DRIVERS\ETC
Windows 2K     =     C:\WINNT\SYSTEM32\DRIVERS\ETC
Win 98/ME     =     C:\WINDOWS

It is a hidden file. Go to any folder and select Tools > Folders Options > View. Check "Show hidden files and folders". Click OK.

5. If you are using Internet Explorer, check if the site is restricted or blocked.  Go to Tools > Internet Options > Security. Hightlight Restricted Sites and see if the blocked site is located there.

Also under Content tab > Content Advisor, check if the site is restricted there. Remove it.
Hi,

Thanks for this advice.  I have done everything you have suggested, in the order suggested and still the problem happens.  I am at my wits end with this

Please Check one more thing
in Internet Options there is "connections......LAN SETTINGS"....go there and see whether you have given any proxy server there. if you are using any new proxy, give the proxy server ip and the port. if you do not use proxy, you can disable it.

check it out and let me know.

Hi,

We don't use a proxy server thanks. For some reason the Internet came back on Sunday evening.  Don't know why but there you go!!!!!

Thanks for your help
baileytibbs, glad you got the internet back.

Hi,

Thanks for your comment.  I never quite know what to do in these circumstances, as the advice I was given didn't directly resolve the issue but it did encourage me to keep trying (rather than simply throwing our server out of the window), especially as I felt I had help from outside experts and eventually I found a solution (if not a cause).

Since last week, our Internet disappeared again.  However, if I change the LAN settings to go via a proxy server, it kicks everything back into life.  Then I can take way the proxy settings and we are back to normal.  The frustrating thing is that I don't know why this happens, especially as we have changed our firewall and router for the second time and the problem returned.

However, I look forward to any suggestions as to how I hand out points for moral support, even if the advice given didn't directly solve my problem.

Thanks again for your help though
