Vista refusing access to network adapters?

Hi Guys,
Most of the time I don't have an issue, however occasionaly my network
adapters look like they have gone down...yet they haven't.
The network detection tools recognise it is connected & I can ping & query
the outside worl from within the terminal; however, IE, Firefox, Win Mail,
no applications detect or use the active network connection.
Running 'diagnose' recognises a problem, but can't resolve it. I've disabled
& re-enabled the network devices & switched between eth & wifi, to no avail.
I recall having tried steps in the past where I have recieved the response
"Access Denied".

This is an OS issue since it hasn't occured running Ubuntu.

Am I alone?

What are you talking about? Are you saying the applications cannot access
the Internet? The network connection is valid in itself in that it can
access the Internet when you pinged a remote site. There is nothing wrong
with the NIC.

You got a router setting there?

What are the IP(s) the machine has when you use IPconfig /all at the Command
Prompt?

And if you are behind a router have taken the machine and directly connected
the machine to the modem to see if applications can connect and work?

If you are able to ping the outside world (www.microsoft.com), then you are
communicating with the internet and all browsers and mail should work. If
this is the case, check your firewall(s) next time the problem occurs. You
may also want to run a spyware/adware/virus scan to make sure something isn't
eating your bandwidth.

If you are just pinging an IP address (64.233.187.99) and not an internet
address, check your DNS servers on your router and/or your computers
configuration (should retrieve them from the router). Sometimes the DNS
(Domain Name Servers) some service providers use are flakey or get bogged down

Good luck.

---My point exactly. It *should*.

As I have previously said, my XP & *nix machines have never had this issue,
so it's not an issue with my network.
I should have mentioned earlier, restarting explorer has no effect. The
computer requires a full restart, which can be a real pain.

Have you tried a hard reset and power down of the router, because the
firmware can become unstable and block one machine's ability to access the
Internet with its solutions, while in the meantime, it will allow another
machine to access the Internet using the same type of solutions?

And you're also stating that the LAN is affected too. What device is the
gateway device for the LAN and WAN, other than, the router?

Sometimes, you have to flash the router with its firmware to correct the
corruption of the firmware, which may be happening in this situation.

I think you have a router issue, where as, the firmware has become
corrupted and is preventing connections, and is causing problems.

It can also be the case that the router can be going defective too, as they
don't last forever, particularly if the router is taking power spikes,
because it's not protected properly.

I'm using a Draytek Vigor router, belkin wireless gateway & safecom switch.
The gateway & switch are connected to the router via eth.
Switch is for LAN, Gateway WLAN.

I'm using DHCP w/o NAT & use either the wifi or eth.
The different MACs & DHCP should rule out the hardware blocking one
particular computer, that & the fact that my internal LAN uses different
routes depending on the interface (wifi/eth) I'm using.

This may all sound confusing or OTT, but I've done it to rule out hardware
issues.
I will also state for the third time, if I run linux of the same computer, I
don't get any problems.

I appreciate the help however,
Doug

Doug, it doesn't matter how many times you state it. The L-word is highly
forbidden in this newsgroup and will be automatically filtered out by
people reading it in their minds.

Matter of fact, this being a Vista newsgroup, there cannot be anything
wrong with Vista. Even if other operating systems don't experience the
problems, it still cannot be a problem with Vista.

To say that a problem with Vista exists is blasphemy around here. =)

Well, I had MS and L word machine on my network behind a router and had the
problem, and I have seen other users with routers that have had the
problem that you're talking about in FW and router NG(s).

It don't take much to push and hold down the Reset button for 30 seconds or
flash the router with its firmware.

What do you have to loose, because nothing else seems to be working out for
you?

Sometimes, the obvious is the obvious, and I don't think it's the O/S that's
causing the problem.

Because if you take that machine out from behind the router and connect it
to the modem, if you can (a direct connection to the Internet), and it works
and the applications you're talking about work, then what?

I have a number of VoIP, WDS and other stuff on the router which I would
rather not have to setup again.
Besides, the LAN routes are direct & don't touch the router, the router is
used purely for WAN; I can remove the router from the network & still have
the problem.
I would be surprised if both my switch & gateway (running different s/w) had
corruptions causing identical problems...
And *again* this doesn't happen if I run another OS on the same machine.
It's Vista, it's Vista, it's Vista!

Doug :-)

Once again, take the machine out from behind the router, connect it to the
modem and find out.

Or is that impossible for you to do?

Without that acid test, what can be said about the satiation? The machine
has an internet connect but the applications running on the machine cannot
connect.

Oh, but wait a minute. What if I take the machine out from behind the
router and try it? Does the problem follow? Is it happening then?

It's called trouble shooting and eliminating all possibilities.

Could it be that you got some Vista FW exception rules enabled that's
blocking those applications?
