DNS Problems

[Chaz G - Mensk88]

Hello Group,
I believe I am having DNS issues. I can be doing whatever on the internet
running usually 3 programs and all the sudden, I'll get Page Load Errors and
my Network Status will go to Just Network (not internet). When I try to
reconnect to Windows Live Messenger, it will diagnose the problem as either
DNS Problems or it will connect and say everything is fine. It usually
happens when I run Zune, WLM, Firefox, Limewire, or any combination of the
listed.

HALP.

Hmm... "Unable to resolve target system name http://www.google.com/."

Hmm... "Unable to resolve target system name http://www.google.com/."

That's because the O/S using a DNS server on the network, ISP's network as
an example, cannot resolve http://www.google.com/ to the IP that belongs to
the site , and without the domain name being resolved to an IP, the machine
cannot access the site.

When the machine has the problem, go to the Command Prompt and enter
IPconfig /all and check the IP the machine is using. If the IP is zero or
starts with 169, then the machine has no valid IP that's going to allow it
to access the Internet. The 169 IP will be assigned if the NIC is configured
to obtain an IP automatically, when there is a failure to obtain or maintain
the IP while it's in use.

For all you know, the NIC could be failing.

OK well I tried the ipconfig and it said my IPv4 is 192.168.0.151(preferred)
Ugh, command prompt is confusing, what should I look for? Sometimes it says
my "Physical Address" is 00-00-00-00-00-00.

What, the machine is behind a router?

It's that IPv4 IP you want to check when you start having trouble looking
for the 169 IP or zeroes.

You may want the check the Gateway IP and the DNS IP that the machine is
using, which is further down in the list of IPconfig information .

If a router is in play, then the router has an Admin screen showing what IP
and Gateway and DNS IP(s) it's using. If a router is in play, then the
router could be having troubles.

I think my router was wonky. I switched it out with my old one and it
connected right away. The one giving me problems was a D-Link DGL-4300.
Supposedly top-of-the-line at it's time. I've noticed wierd things with it a
lot. It says I had Firmware Ver. 1.8 but on D-Link's support site, they only
had 1.7 for download... I don't know. Guess my router just got old and
senile. That sucks...
