we have a master computer at work that runs three other computers on a
network. the internet is boradband but the trouble for the past week has
been that we can't seem to go to any websites, if we're lucky we might be
able to access Google or another site but thats about it. I've checked the
what I know to see if there were any problems I recognise and can't find
any. The computer is connecting OK to the internet but just can't access
sites. I've run CW Shredder (which turned up a couple of trojans that it
removed and it's fine now) and I ran Anti-virus scan (Nortons) and its all
clear but the problem still remains. Can somebody offer suggestions or help
regarding this matter.
 
Could be an ISP issue.

Go to the command prompt and type:

Tracert google.com

That should give you a 30 hop trace to the server, pay
attention to any that come up unresolved as this can
indicate routers along the way that are failing and
dropping the signal. Also you may want to ping the same
server and see if there's any abnormal numbers.

ping google.com (on cable modem I get ~45ms to Google)

If it's your ISP you can contact them to see if they can
resolve the issue. If it's not then I deferr to others
with more exerptise in networking matters.
 
Also need to add, the boss phoned the ISP and they insist there is nothing
wrong on their end, they say it's something to do with our computer...thus
the frustration we all feel regarding this problem and not being able to
rectify it...
 
Sorry for some lack of understanding regarding tech terms but what do you
mean by "ping" Google?
 
with a lack of knowledge in basic commands i suggest you find a techy to
assist you in person.

now to do a "ping" command to a specific domain, you click "start" then
"run" and enter the word "cmd" (without quotes). now you have a dos
prompt.(black page)
here you type: "ping google.com" (again without the quotes) a list of text
will go down the page. let these guys know the results (ie timed out).
they may be able to help you a bit more.

like i said though with your lack of understanding i do not suggest you go
around tampering with servers and networks.

CWShredder and Norton is not enough. I'd also suggest SpyBot and AdAware.
It also sound like your HOSTS file may have been tampered with. You'll
find The HOSTS file in windows\system32\drivers\etc. Open it with
notepad. By default it should look like this:
# 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

The only uncommented line should be that last one. Be sure you check
all the way to the bottom of the page. I've seen viruses (or other types
of malware) that will put a few pages of blank lines below and then have
the dirty stuff way at the end. Namely entries which blocks sites from
being accessible.
If it doesn't look right, then rename it to HOSTS.tmp or something and
try browsing again. Don't delete it, because there are some adware
blocking programs that use the hosts file to block ads. Any site name
that follows a 127.0.0.1 is blocked.
Hope this helps.
 
the more you play around the more you learn, that's the best part ;)
as long as your carfull and you backup things should be fine.
good-luck
 
It doesn't get much more basic than a command prompt and ping.

Thanks, my understanding is thorough of basic stuff but more techy stuff,
confounds me.
