I wonder whether anyone here can shed light on a little problem that's
been bothering me since I upgraded my laptop.
I use my laptop (mostly) at one of two different locations. At each
location I have a wired connection to an ADSL router, getting an IP
address etc. by DHCP from the router. The routers are different makes
(one is a Draytek 2600, the other a Solwise SAR715) but are configured
with the same address on the 192.168 subnet.
With my old laptop (IBM Thinkpad T22 running Win2k as limited user,
with Zone Alarm (an old version ... 5.5-something?)) this "just worked"
at both locations. With the new laptop (Toshiba Tecra M10-10i running
XP (32-bit) as limited user, XP firewall) everything works fine at one
location (the one with the Draytek router) but at the other location
everything starts well -- I get a network connection when I power up
the PC and can collect EMail, browse the web, etc. -- but I lose
internet connection after some minutes.
When I say "lose connection", what actually seems to be happening is
that the PC loses its connection to DNS and can't resolve names. This
is easily cured by opening a command prompt "Run as" an administrator
and running "ipconfig /renew". After that has been done once the 'net
connection continues to work indefinitely. Interestingly, if I open a
command prompt immediately on starting up and run "ipconfig /all" I do
NOT see a DNS address listed, but names are resolved for at least a few
minutes. After doing the "/renew" a "/all" does list a DNS server (the
router's internal server).
I also occasionally run Debian Linux (64-bit version) on the new
laptop, and the problem does not seem to occur there. This leads me to
believe that the cause is something to do with the Windows
configuration or software used on Windows -- but what? I'd really like
to get to the bottom of this as I'm tired of opening up administrator
windows and running ipconfig all the time!
domain, then just manually edit the wifi adapters connection TCP/IP
properties and enter the IP addresses of OpenDNS's DNS servers
(www.opendns.com) which are:
208.67.222.222
208.67.220.220
Not only does that solve the problem but it will also protect you
against DNS poisoning and a whole raft of other stuff..
You might find they work faster than your ISPs too.

OpenDNS does not protect you against anything unless you have a static
IP and set up an account. Some services you need to pay for. Stop being
misleading through your lack of knowledge/experience. OpenDNS is NOT
to be confused with any type of firewall. It does not protect a computer or
router against DNS poisoning. The 2wire 2700 series is a good example of
how it would not work in the way you suggest.
If you want to prevent advert sites and other such strange ones you need to
use a HOSTS list, Google for it, there are many about.
