Vista - Vista Intermittent Network Connection Problems

I am have an intermittent network problem with Vista Home Premium on an ACER
laptop. Upon bootup the network connection appears fine. The browser will
make a good connection anywhere the first time. But sometimes after the first
connection the browser cannot connect anywhere.At this point no windows
application can connect anywhere on the WEB including windows mail.
The Windows Network Diagnostics provides the message: "There may be a
problem withyour Domain Name Server (DNS) configuration. Windows failed to
find the well known host 'www.microsoft.com' using DNS. The server maybe be
down"
But, I can, in a DOS command window ping 'www.microsoft.com' and the IP
address is resolved with no difficulty (although that host does not respond
to Ping).
It does not matter which browser I use either IE Ethernet Explorer or
Mozilla FireFox, the symptoms are the same. I have attempted turning off the
firewall and pop-up blockers to no avail.
I took the computer back to the store service departpartment (Best But &
Geek Squad); they ran diagnostics that verified that there were no hardware
problems and that problems were in Windows.
What can I do to fix this problem?

I have seen the exact same behavior. An intermittent inability to establish any new connections to things on the Internet... mail servers, web server, chat services, etc. Any connections already established are fine however. I can ping, and look up IP addresses, but that's it. Additionally, I have a friend who also has Vista and see the same intermittent behavior.

Basically, I just have to wait until Vista "comes back", to continue those activities or simply reboot. This really smells like a bug in Windows to me... but have no idea how to solve it, or if there is a solution for it.

news:GMac.2xf9i5@xxxxxx-mx.forums.net...Can you ping addresses that are a name instead of four numbers?
If not, it could be problems reaching your ISP's DNS server.

Yes, I can ping names (i.e. Yahoo.com) just fine. If I try to ping something that doesn't respond to pings, such as microsoft.com, it still shows me the IP address for Microsoft.com. For that reason, I really believe it's not a DNS issue.

I'll be browsing happily along and then suddenly get the good old "Server is not available" message (or some such) and then I can no longer browse or establish new connections to any network (even internal) resources. My connections to instant messenger services are all intact and usable. If I disconnect from any service, I am unable to reconnect. Same goes for any remote desktop sessions I've established (like from work to home). As long as I stay connected I'm fine. So sometimes, I'll actually use my home computer to continue doing any Google searches I'm doing until my Vista box's networking comes back, which it seems to do within about a half an hour.

It's a rather irritating problem, and clearly not isolated to my installation.

Very fustrating that my old XP machine is so much more reliable.

When you ping an outside addresses Does it respond? ie ping google.com
if that doesn't work then it could be a dns issue. try pinging 4.2.2.2.
If that works, but pinging by name doesn't it is definately a dns
problem, however, if you are able to ping addresses on the web eaither
by name or address you are connected to the web. At this point I would
try disabling my anti-virus program or firewall program and check again
if that is the case.

I am having this same problem with Vista connected via a cat 5 wire to the router.
I can use the browser for about a minute and then it fails saying windows fialed to find the well known xxxxxxxxx using DNS
Did anybody solve this issue.. From October ???
WOW, WISH we had XP on this machine.
Thanks in advance

As far as I know no one has offered a solution since I first posted in Sept.
'07. But I have wondered about the commercials running on Comcast Cable
advising To power down and then power back up. What's that all about?

I've been having the exact same problem for about a year now. I'll be
browsing the internet with no problems for about 2-3 hours, when
suddenly any page I go to brings up 'server is not available'. But like
other people said here, anything I had open still works, like any kind
of instant messaging program, or any downloads. The only solutions I've
found is either to reset my laptop, or wait around for about 30 minutes
till my connection comes back.

I know the last post was last year, but if any of you guys solved the
problem, please let me know.
