Clearing my DNS cache

Yesterday we had to rename our nameservers and while everything is looking good in terms of email etc., there's one machine that for some reason cannot connect to the website.

If you head out to countryshowdown.com, you'll see the site that was a problem yesterday. It's now coming up fine, obviously, but on my computer when I type in "countryshowdown.com," the computer brings up specialpromotionsinc.com.

I've cleared my cache (Tools / Internet Options / Browsing History / Delete) and I've also run the ipconfig/dnsflush command and I'm still getting specialpromotionsinc.com everytime I try to pull up countryshowdown.com.

What's going on? Where does "specialpromotionsinc.com" come from? Is there a setting somewhere that dictates a particular url to be pulled up with the computer can't find a specific site? And, how do I clear my computer's "memory" so that it doesn't attempt to find countryshowdown.com according to it's now antiquated nameserver?

does that machine have any records in its hosts file that maps to the old DNS server names?
C:\Windows\System32\drivers\etc\host

Have you checked that machine for spyware?

Here's what was written on the host file (the old nameserver was called "echoframe":

# 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

127.0.0.1       .psf


I've got AVG on the computer so I want to believe that spyware isn't an issue.

That really sounds like adware.  Try a more specialized tool like Malwarebytes.

If that doesn't come up with anything, see if there is a file named just LMHOSTS (not LMHOSTS.SAM) in the same directory as the HOSTS file.  If so, see if it contains any entries for the name countryshowdown.com.

The correct command to clear the DNS cache is ipconfig /flushdns.  Also run nbtstat -R to clear the NetBIOS cache.

Alright folks!

I ran the ipconfig/flushdns command again, then rebooted. This time, everything is working fine!

Thanks for the input!
