All of a sudden I can't open a web site that I used to go
to all the time. It's
www.reviewjournal.com and I can
access it from my laptop on my home network but not my
desktop. I tried flushing the dns at ipconfig but that
didn't fix the problem. I need to access this site for
my job and I'm very frustrated. Please help!
It may be a problem with the DNS that you are using on your desktop.
Does the same lookup get done if you try pinging that server name
in each case? Don't worry if the request times out; you are only
doing it to see if the lookup is available.
ping
www.reviewjournal.com -n 1
If that works perhaps there is a timing problem with the DNS.
That often seems to be the case when the server name is an alias
for a real server name but that doesn't seem to be the case with
this name:
<example nslookup result>
Non-authoritative answer:
Name:
www.reviewjournal.com
Address: 12.9.217.42
</example nslookup result>
In any case what you could do is add an entry to your HOSTS file
for this name and see if that works any better.
You can see the syntax given in the HOSTS.SAM file:
Address in column 1, at least one space and then the symbolic name.
<example line to add to HOSTS>
12.9.217.42
www.reviewjournal.com
</example line to add to HOSTS>
Depending on your OS for the override to work it must go in the correct
HOSTS file (uppercase, no extension) in the correct subdirectory
and a reboot may be necessary to activate it. E.g. NT4 required a reboot,
XP doesn't.
If that works you will have some information to present to your ISP
in order to get it fixed eventually. You don't want to leave DNS overrides
in HOSTS indefinitely in case something later changes after you have
forgotten about the override.
Another possibility is that the lookup is fine but the routing is different
in each case. You could try comparing the output from
tracert
www.reviewjournal.com
done on each system to see if there are any significant timing differences.
Unfortunately because of all the morons who have exploited ICMP
in their denial-of-service attacks the diagnostic value of these commands
has been greatly depreciated as sites have taken counter measures.
There may be some clues you can still get from them but not as much
as was once possible.
Good luck
