I am running Windows Vista Home Premium. A web site that I visit
daily,
www.pcmag.com, is suddenly inaccessible. I can log into other
sites
without a
problem, but when I try to access
www.pcmag.com, either through
my
Favorites
or by typing in the URL directly, I get a long delay followed by
the
"Internet Explorer cannot display this web page." This problem
cropped
up
suddenly and for no apparent reason. I can access the site on
other
computers
on my network, so I'm the only one having this problem. Any
suggestions?
Sounds like you may need to clear the DNS Resolver Cache. Try
IPCONFIG
/FLUSHDNS from an elevated command prompt and see if that doesn't
correct the problem.
I followed your instructions and restarted my browser but the
problem
is
still there. Another oddity; at times when I type the URL into the
address
bar, it will take me to
www.google.com and display the search
results
for
"
www.pcmag.com." The top result, of course, is a link to the PC
Magazine web
site, which I select in the hope that it will work - it doesn't.
What
now?
Thanks for the suggestion - I thought it would work!
The oddity with Google makes it sound even more like a DNS problem.
Try
going to a command prompt and typing "ping
www.pcmag.com" and post
back
with the results.
Here are the ping results. Note that "pcmag.com" resulted in a
response, but
"
www.pcmag.com" timed out? Significant? Thanks!
Regards,
Ron

Somewhere along the line your DNS lookup for
www.pcmag.com is going
wrong. Since it works from other PCs on the network, it may be that
you are using different DNS servers somehow. Do an IPCONFIG /ALL on
your PC and on a PC that can get to the site and compare the DNS Servers
entries.
Another possibility is that you have an entry in your
C:\WINDOWS\system32\drivers\etc\hosts file that is pointing
www.pcmag.com to the wrong IP address. It is just a text file, so you
can edit it with notepad and see if there is a line with that IP Address
and
www.pcmag.com on it. If there is one, just delete that line and
save the file. FYI, you'll need to be running notepad as administrator
to be able to save changes to the file.
Also, when I had you try IPCONFIG /FLUSHDNS, what was the response? Was
there an error, or did it say "Successfully flushed the DNS Resolver
Cache"?

Dave
