I have exactly this problem too!
Some facts about this problem:
- IE and other browsers stop working for no obvious reason
- Not even local web servers can be reached (like 192.168.0.1)
- This can happen at any time, not correlated to any special program being used
- *Sometimes* (very seldom) it starts working again, after 5-30 minutes
- Microsoft Mail stops working at the same time.
- Windows Update stops working (it still finds new updates and say \"There are new updates\" and so on, but when trying to install then it bombs out with a 8-digit hexadecimal error code).
- The help text for the error code is wrong. It is not a dns problem or a connection problem.
- MSN/Windows Live Messenger stops working *sometimes* but not always
- I can still ping hosts on the internet, and DNS works just fine
- This happens on Vista (I have Vista Business)
What i have tried:
- Logging out and logging in again: does not solve the problem
- Disconnecting and reconnecting network: does not solve the problem
- Restarting router etc: does not solve the problem
- Disabling the windows firewall: does not solve the problem
- Disabling and enabling network interface: does not solve the problem
- Suspend/sleep mode and wake up again: does not solve the problem
- Stopping and restarting all \"network\"-ish services: does not solve the problem
What works?
- Reboot. Nothing else.
What this is NOT:
- This is not a router problem/external network problem
- This is not a DNS problem (not external, not internal)
- This is not a network adapter driver problem
- This is not a hardware problem
- This is not a bug in IE
- This is not a bug in the DNS cache service
So, what is this?
- This is a bug in Vista. A very annoying one!
If someone at M$ reads this, then PLEASE do something about this.
I am thinking about deleting Vista and installing XP or something. This is just to sucky.
I am suffering also.
I have the same symptoms, Randomly i will be surfing the internet, and i will get Disconnected. All P2P programs, MSN, Download managers, even Ping and TRACERT still work.. EVEN Microsoft Remote terminal servicees and World of Warcraft!!
Ocasionally after SEVERAL hours while playing World of Warcraft, and not wanting to restart/reboot. I will continue to play, and magically my internet browsers start working again.
It is NOT a bug in the DNS cache. I have cleared mine,
It is NOT the router or the cable modem, because it only affects one machine. The other computer in the house can still surf the internet. Also my Xbox 360 still connects.
It is not Comcast, It is not my network card... I have tried connecting multiple nick's including a USB wireless, and an onboard wireless, including my sweet motherboard has 2 gig ethernet ports.
I can still browse files on my home network in other rooms.
Not only that my IIS still responds to outgoing / incoming requests. So people surfing the internet webpages on my computer still have access.
But if i surf webpages on
http://localhost/index.asp IT DOES NOT WORK!!!!
Nor does
http://192.168.0.1/ <-- router
I have tried Mozilla, and IE.... both quit at exactly the same time.
What i have tried is
ipconfig /renew
ipconfig /renew all
ipconfig /flushdns
ipconfig /release followed by ipconfig /renew
Logging off the user and then logging back in.
Unplugging the cable modem, and back in
Unplugging the router and then back in
unplugging the network card, and into another network card, or even enabling my wireless or using any other nic available.
I ran something i saw on another page where it had me type this in a Dos command
netsh int ip reset c:\tcpiprebuild.log
This did not work etither.
Putting my computer in Suspend
Putting my computer in Sleep
Disabling my fire wall,
Disabling Net Limiter
UnInstalling Net Limiter
My system is a 5200+ Dual core AMD
Motherboard M2N32-SLI Delux Wireless
Memory is 4Gigs
Video card: Nvidia 8800 GT, Nvidia 7800 XFX (not in SLI mode)
OS: Vista Ultimate Retail 64 bit
DVDRW x 1 DVDRW + Blu-Ray / HDDVD drive x 1
Hard drive space 5.4 Terabytes (yes im a hard drive space nut... but i got an awesome deal on 1 TByte drives so i bought 4 of them and raided em.)
The only thing i HAVENT tried is the stuff i read about "
MAX Concurrent TCP Connection Attempt Limit for Windows" which i have found on other pages. Since microsoft included this "feature" ... and the ONLY fix is to download some 3rd party "hacked" tcpip driver.... i havent wanted to do this because it sounds like it could be a dangerous way to get your computer hacked with malicious trojans or spyware. *********************** THE ONLY SURE-FIRE WAY to instantly start surfing the internet, is a REBOOT or wait 20-30 minutes. (or even longer).. thats the ONLY WAY to get the web-browsers working again. *********************** Also this started happening within the last 4 months, but for 1 year running vista it was fine with all the daily updates. So i am wondering if it was one of the helpful "updates" from microsoft. Is there some other way? This is getting really annoying restarting my computer over and over again, just to browse the internet. Oh and magmatrix.... dont install XP to fix this... because if you are getting this on your vista machine, you will most likely get this on your xp machine too... because the same "concurrent TCP Connection Attempt limit" is also on XP.... and my XP machine suffered with this problem also. (that is if its the max concurent tcp connection limit that is the problem) infact.... on XP its even smaller than its on Vista. The only other thing i havent tried..... Re-Installing my OS *(what a pain that will be) Hopefully someone sees this and comes to our aid, and we figure this out without having to re-install an OS. Or install some hacked version of the tcpip dll Even if i had to use a binary editor and hack my own TCPIP.dll driver i would do it. (within reason) I would do practically ANYTHING so that i don't have to re-install my OS (oh and i dont have any spybots or virus's or trojans or spyware installed ... ive ran checks with norton and other spyware removers, and un-installed them after the scan)
