Suddenly i lost my network connection.

I ping other devices on my net, but get timeouts. I could only ping the PCs own IP.
I DO get an IP when i boot, but when i try to surf the net or get on MSN nothing happens. And when i check network connections, it looks like there have been a little bit of traffic both ways.
I tried to do a "system restore", it didn't work.
I ran AVG antivirus, it didn't find anything.
I tried to change the net-card, it didn't work either.
I tried swapping cables with a PC that is on the net, right next to this PC, and it didn't make it work either.
When i start smartFTP, it writes that is has connected, but after a few moments, it says something like "FTP connected has been blocked by local program"
I tried to reboot in "safe mode" and then i got my network connection!

What is wrong?? is some program blocking for my access to the net?? :( and how do i localize it?

I really hope someone can help me. Anything will help!!
 
netsh int ip reset c:\resetlog.txt

Also try this
You can reset the LSP feature of TCP/IP with this command:

netsh winsock reset catalog

Also look up the following if you have any internet acces WinsockXPfix.exe and LSPFix.exe
 
Wow thanks alot!!!

You saved my life!!!

I used this one, and it worked:
netsh winsock reset catalog

I don't know what it did, i only heard people talking about winsock, but never really knew what it is. Maybe i should look it up.

Thanks alot!!!!!!
 
Basically, Winsock is MS's way of connecting TCP/IP connections (the basic Internet protocol) to each other and/or the Internet.

Up until XP, you could simply uninstall/reinstall this protocol yourself using just Network Connection Properties. Easy as pie. Now, it's a bit more difficult to rebuild the TCP/IP stack, as you've found out.

Just another way MS protects us from ourselves...and keeps tech forums (and paid technicians) alive!

I was only connected to the net for 20 seconds, enough to see google, and to search something random. *crying*

These two lines seem to work but only for 20 seconds after i reboot:
netsh int ip reset c:\resetlog.txt
netsh winsock reset catalog

After 20 seconds i get kicked off.

Sometimes when i enter an URL in IE, it looks like it finds the IP of that URL in the status. So maybe it has access to the DNS, but not for the real html content. I'm not sure though.

I really dont know what to do now, i spent 7 hours nonstop trying all kinds of things and it's still not working.

Any ideas at all, will help. Thanks!!!!
 
I was all happy for you, but then I read your last comment. Bummer.

Try to do a ping and then a trace route (tracert) to something like at the cmd prompt and post what it tells you. I guess you only need to do the tracert if the ping is successfull

You could also try to put in an IP address and DNS servers manually to see if that is the issue. Try these two DNS servers (from Comcast)
68.87.77.130
68.87.72.130

Have you checked for spyware - I've seen spyware kill IP connectivity but normally when you remove it.

If all else fails, do you have another network card to try - just in case it's somehow hardware-related??
 
Thanks alot

I tried this guide even if the symptom is not the same, but i read about it in a thread similar to mine:

and it says that i click "Start", "Run", "msinfo32" and then expand "Components", "Network", "Protocol", then i should have exactly 10 sections... i had 12...

So, i followed the instruction, and reinstalled it to get 10, but now i only got 4!?

Some people were talking about repairing windows with the installation disk, but i cant find it on the disk. I'm on the edge of reinstalling it all, but it will take all weekend :( and i have to find my codes, some of them are in emails, it will be horrible. :( Can i somehow install windows on top of the old installation without having to install every program afterwards again?
 
I will try your advised, I'm a bit drained right now, i have been working on this computer for 1 hours now! :(

I already tried with a new netcard, but it didn't change anything.

Thanks alot for you attention!!

I will try the tracert thing now.
 
Hi again, it wouldn't let me "tracert", i only get timeouts.

Spyware, I both ran SpyBotS&D (updated in safemode) and Ad-aware (newest version downloaded in safe mode, but i couldn't get it updated)

Anyway i didn't find any spyware.

I think they problem could be something to do with the TCP/IP-thing i mentioned above... that i got either 4 or 17 sections instead of exactly 10 as MS want me to have - right now it's 17, after running LSPfix.exe and winsockxpfix.exe a moment ago it was only 4.

Btw i manage to stay online.. maybe 30 seconds now.

Thanks ALOT for your attention.

*11 hours, not 1 hour

 
Case closed for now. I gave up and is reinstalling windows. :(

Thanks ALOT everyone for your attention. :))
