Something is realy wrong with network in Vista... really.

May be not exactly in Vista. Perhaps in network/motherboard drivers for Vista.

I have ASRock AliveNF4G-DVI motherboard with integrated LAN.
Also I have wireless card for home ad-hoc connection with laptop, RALINK 2500 with WinXP(!) drivers (Vista unable to properly identify this card).

Main NIC is binded to static IP given by provider. Main connection is shared. Ad-hoc network is created by standard Vista tools. All connectioons are firewalled.

So, here is my problem.

1-2 times per day I'm loosing ability to use internet. It looks like something blocking browsers (any) or ability to lookup names. I can't: browse internet sites, access FTP, even IIS on localhost(!) becames unaccessible(?!?!). BUT!!!
All existing connections made by WLM, Skype, eMule are active and valid... I even can connect to this PC from external PC using RemoteDesktop!

Ok. After reboot all works well for some time.

I've already turned off "TCPIP auto turning", reduced number of active connection in eMule (bloody Event 4226!). Increased number of connections in TCPIP parameters in registry (very not sure what this was fixed in Vista). But problem still exists.

Now I've turned off firewall and waiting for results...

Weirdest thing is - there is no network related messages in EventLog! But I have strange messages about crashes of WLM and VERY strange message reporting "There is no PCI devices reported on slot 0..." (or sort of).

Second problem isn't so big, but annoying. Ad-hoc wireless network. Yes, it's much more stable than on WinXP. But if connection is lost, it goes forever. I can't just reconnect. I have to remove all settings and setup from scratch again and again.

I have something similar to that. Happened a lot during the beta, for some reason, all name resolutions would fail. I could browse the net fine though, IE would resolve all addresses, but everything else couldn't. Ping couldn't resolve, and hence Outlook died, and Windows Mail died etc.

The only way I could fix it was repeatedly going "ipconfig /flushdns" all the time, giving it a little while and it would start resolving names. Very strange and still haven't figured out what causes it. Not really bad anymore it seems, though I've seen it happen a few times in Outlook.

I hope the stack was improved between RC1 and RTM. With RC1 I can't reach the website of my bank, but I'm holding out for the next Longhorn Server Beta, because I don't want to reinstall every one or two weeks.

How might I do that? I unchecked it in the adapter properties, but that didn't fix it.

I'm using RTM from MSDN...

Same thing on rc2. Sometimes when I use bittorent client I can't connect to any www ( proxy or not - doesn't matter ) but torrents work.

I get the same problem 3-4 times a week, only a reboot fixes it. It seems to stop only my browsers from working (IE + FF) but msn chat, Outlook (via https) still works! which makes no sense!

A couple other times my primary wireless card had its address reset to static (x.x.0.1) instead of DHCP - but when that happened everything died and I could fix it.

So, I'm not stupid hand-less moron and doesn't swearing at Vista for nothing.

Thank you guys!


What is your hardware (motherboard, chipsets, NICs)?


Actually, my system without firewall still working fine, ~6 hours with  running eMule. We'll see...

I had this problem in the betas, dns completely failing.

 ipconfig /flushdns

That did the trick for me.

No, "/flushdns" doesn't revives network connection. WindowsFirewall not quilty too. My connection disappears even with disabled firewall. IPV6 protocol also not guilty.

But I FOUND what to restart to return network without rebooting!

"Network Connections" service (quite logically ). It restarts "Internet Connection Sharing" too. After restarting listed services all browsers ability to browse came back!


This definately IS a Vista RTM bug!


MS! Where I can find any logs made by those 2 services? There is no any entries in EventLog!

Not working for me Flushing dns too

I had the misfortune of disabling that service while I was disabling un needed services.... took a while to discover why all net traffic was failing on my pvr, since I didn't immediately use the box after I disabled the services.

Hmmm... Looks like there is more than one bug in network in Vista.
What I've done:
1. Create parameter DWORD "TcpNumConnections" in registry HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\<YOUR CONNECTION HERE> with quite large number (don't think it working, in XP this parameter doesn't working but listed in documentation)
2. Run "ipconfig /flushdns" from command line
3. Turn off "auto tuning". Run "netsh interface tcp set global autotuninglevel=disabled" from command line
4. Uncheck IPv6 protocol in network connection properties
5. Uncheck all "Link..." in network connection properties
6. Disable/Enable Network connection
7. Disable all other network connections
8. Disable/Enable Network connection again
9. Restart "Network Connections" service (including Internet Connection Sharing service)

It helped me to restore network without rebooting whole system. May you need different sequence.

Good. I've just lost network again and got a chance to find services to restart more precisely. It was "Internet Connection Sharing" ONLY. After service restart network came back. No entries in EventLog! [6]

Wow!!!

I've just tried to open "Network and Sharing Center". Suddenly "Glass was broken" (how "glass" is connected to network services!?!?!?!?! ), windows reported about some service crash ("Faulting application svchost.exe_CscService, version 6.0.6000.16386, time stamp 0x4549adc4, faulting module unknown, version 0.0.0.0, time stamp 0x00000000, exception code 0xc0000005, fault offset 0x00000000, process id 0x464, application start time 0x01c72415ee53230c.")

Sharing tab from network connection disappears! And small icon in tray reporting me about bloody DEP! Cool! I like this! It sounds like "our software isn't compatible with our software!" (signed by MS). How to completely disable this bloody DEP?!?!?

BLOODY HELL!!! God damn Vista!

I've lost connection again! Even services restart doesn't helps now!

After rebooting things became even worse! Screen resolution was reduced to 640x480 and glass was disabled! I have to manually restore it! Why? Bloody hell, why?

Only full system reboot can properly fix network. And looks like ATI video driver has problems too...

Madness...

Did it ever occur to you that this may be the cause of all your problems?
