OK, I finally solved mine.

It was a piece of McAfee firewall left after an uninstall because the owner had put BOTH McAfee & Nortons on at the same time, and the Nortons tried to uninstall the McAfee unsuccessfully, but enough so that it didn't show anywhere except the hidden processes and in the Registry. (He swore to me that he hadn't changed anything in months, and only admitted this after I told him what I'd found!)

I uninstalled Nortons and then used the McAfee Cleaner Tool to remove the remnants of that. And now we are all working. I left all the other mods in place too cause what home user needs IPv6 anyway??

In response to the last poster, if you had read through all the posts you would have seen that in VISTA it is NOT POSSIBLE to Uninstall TCPIP IPv6. Try it for yourself. You have to edit the Registry so that Vista "ignores" it. Search the MSKB for "Uninstall IPv6 from Vista".

I have a freshly installed Vista Business, it only has firefox, gtalk and some drivers on it. I had a dlink card which worked almost ok (the real problem for me is the router). Even so, it was working and I could connect to the internet, barring the packet loss to the router.

I tried installing a second wireless card (the two cards were a system which used to work on my old XP - I can't change the router unfortunately), which resulted in a total crash of the networking(the problem in this thread), so I uninstalled the second card. What happened next was that the dlink started to work, and it continued to do so for about 30 minutes, at which point the above mentioned error appeared. I must mention that I noticed it was in connection to very heavy packet loss.

The really strange thing is that I did _nothing_ to it - it just decided to stop working at some point. I tried the default Vista stuff, like repairing and all, but at some point gave up and started reading this thread on another computer to see if there was a solution. Funnily enough, when I was on the 3rd or so page, I suddenly notice the computer with the problem started working again (nothing i did). I wonder how long this will last...

I had this issue in which I couldn't ping "general failure". My windows firewall was disabled but I had Trend Micro's Internet Security Pro installed. I modified the network and firewall controls from Medium to Low and was able to ping, etc.

I just upgraded from Vista Home Premium to Ultimate. My internet was working fine untill I upgraded. Vista shows that I am online(an internet connection icon on taskbar) but I cannot access any web site. No other program can access internet. I can ping yahoo and can access my local network. I am an advanced user and never ask for help in these forums. I always search it out for my self, but this one has me stumped. I have tried all the suggestions here , but to no avail. HELP!!!

Hi and welcome. Go back and check your firewall.

[Shwaa]

Had the same problem with my Vista, one minute working browings alls fine
then reset and bung!

went through vista's diagnoses which i might add utterly useless
ipconfig would not get an ip
but the really anyoing thing was i could see a network map our my flat with the router and my flatmates laptop

reset the tcp/ip stack and worked fine no errors, or so i thought i could see my ping my flatmates laptop but only by name and got back an ipv6 address. ah ha v4 is to blame.
so i tried the netsh on v4 but got 'reseting echo request failed'

did a bit of searching and found that tcp/ip (v4) could have been corrupted.

uninstalled ALL network devices including my VMWare ones and reset
bingo I am downloading dreamscenes to my hearts content

much better than resorting to reinstalling vista

hope this helps

I have a specific problem on my Vista Ultimate..

I have 2 network adapters, one is local network, have just ip address and mask set on it, and the second one connections receive a DHCP address from my provider. Everything works fine, but in a moment the network disappears.. ip addresses are there, but no ping.. and just resetting the second network adapter works. What could be the problem? I don't have any firewall(just windows) I'm relly mess up with this already...
it may dissapear, may not.. (my cable modem is alright and the provider is fine too.. no problems found.. it's something with soft/hardware)

Hi

Did computertechie ever fix his problem? I have just installed Vista on a new Dell latitiude D830 to test in our corp environment.

All was working fine for a couple of weeks and then suddenly out of the blue I stopped getting DHCP addresses after putting the computer into sleep mode, thought this was strange but a reboot always seemed to fix it.

It went on like that for a few days and then the reboot failed to fix it. Now DHCP just won't work either on my corp lan at work with a M$ DHCP server or at home on my wirless router. The only way I can get on to a network is to give myself a static v4 IP address.

I have tried loads of things including most of the items suggested on this thread, and it is REALLY starting to get on my nerves now !!!

I am going to download Vista SP1 tomorrow and see if that clears it up but wanted to know

1.) If computertechie had managed to resolve his issue as it sounds pretty much identical

2.) if anyone else having the same issue tried Vista SP1

Any help to a very frustrated Vista user would be greatly appreciated

Thanks all

to be honest - none of above helped me to solve this DHCP vs VISTA bug . Personaly in my case after each windows boot I had to disable/enable network adapter, then, repeat this action every hour because of lost connection. It's pain you know....

so, after digging deeper with wireshark I've found a solution.

1st - let's emulate a problem (it's not random as most of you thought above).

make sure your internet connection is working somehow (dead end? then skip to "solution"), then:
run start->run->cmd->ping x.x.x.x -t , where x.x.x.x is your gateway.
You should see successful icmp responses. keep this window open. now, go to your device manager:
start->computer->properties->device manager, select your network adapter and from the right click choose "Update Driver Software".

now look ant comman-prompt - "timeouts, isn't it?"

solution:
run internet explorer, go to Tools->Internet Options->Connections->LAN settings. Uncheck "Automaticaly detect settings".

the problem lies within detection of automatic configuration script(which, most likely, isn't available) - dns name resolution requests and dhcp requests interact not as they should. So, every time some internal vista's application tries to access internet - you loose your connection no matter if you're browsing google, watching youtube movies, gaming or whatever...

if you need more information on this subject - download wireshark and read http://www.isaserver.org/articles/IS...utoConfig.html

Same bloody problem!

But I FINALLY FIXED IT!

I was overclocking a new processor and must have rebooted a hundred times. When I finally gave up, reset to stock settings and booted Vista, I couldn't get a DHCP address. I tried many, many things, and after I restored my original vista installation, since reinstalling didn't work, I tried plugging in another network card, then plugged the network cable into that card and started Windows.

I couldn't believe that Vista didn't have a driver ready to load for the venerable 3C509C, so I got pissed and thought I'd try plugging the network cable back into the onboard NIC, and IT FINALLY WORKED!

I got an IP and could get on the net right away. So is that all you have to do? Shut down the computer and boot with the network cable unplugged? Mighty weird, I must say.

Guys/Gals, listen. Do what Supacon says above. This is the only thing that has worked for me and it has been flawless since. Unplug any patch cables, reset your bios to default settings, reboot into the latest Windows Millennium (VISTA!!!), and then reconnect your patch cable to receive your brand new non-apipa IP. If Microsoft releases a "valid" directX 10 for XP, I am soooo going back.

Nothing in this thread has worked for me. This behavior exists on three different network adapters on an HP laptop with Vista Home Premium.

I've experienced the same behavior as posted originally: Cannot receive an IP from any source (wireless, LAN, EVDO modem, different networks and routers). When attempting a ping I get the same error 1231.

I think I'll be opening a Microsoft support case about this issue and will let everyone know what happens.

[scurler68]

I had the same problem. We had an HP Slimline Desktop in our office running Vista Business Ultimate. It was running fine until today. The only thing that had changed was a recent Windows update, but it could no longer acquire an IP address on either the wired or wireless interface. It also couldn't ping the loopback. And even setting a static IP didn't allow it to ping the router, get on the internet, or discover the other computers on the workgroup that it had previously been networking with just fine.

So first, I uninstalled the update. That didn't do it. Then I tried running in Safe Mode with Networking. Then I tried selective startup. Then I tried System Restore, twice. Then I tried the netsh int ip reset and winsock reset commands. Then I tried the registry changes. Then I tried disabling IPv6. Then I rebooted without the network cable plugged in, then plugged it back in when it came back up. I tried uinstalling and reinstalling the two network cards using updated drivers. I tried everything I could find on this bulletin board and others, and spent 2 hours on the phone with HP tech support. All to no avail. HP finally told me that I would have to reinstall the O/S and said they couldn't help me anymore until I tried that.

Finally, as a last ditch effort, I downloaded the Norton Removal Tool and used it to uninstall Norton Internet Security 2008 and poof! I was back in business....4 hours later.

So WTF? Doesn't Symantec QA their products anymore? Seriously...after the trouble that I've also had with clients on Norton 360, this is the last time I will recommend a Symantec product.

Good luck. I hope this helps.

Thanks that did the job. It's crazy because it worked fine, I took my laptop with me over the weekend and never hooked it up to the internet then I got it back home and poof it just stopped working.
