Re: Web/HTTP access doesn't work, PING does

said by MineCoast:

Try the following on the command line.

Netsh int ip reset reset.log (the command above is incorrect)

netsh int ip delete arpcache (this doesn't appear to have been tried)

Reboot after running these. It should resolve your issue.

If that does not resolve issue, uninstall/reinstall NIC drivers. Disable TCP/IP Version 6 if it's installed as well.
netsh int ip reset reset.log or netsh int ip reset resetlog.txt will both work.

Its not his NIC drivers - the NIC works fine in safemode.

As I said before - there is software loading in regular mode that is interfering with the HTTP that doesn't load in safemode.

If you can't seem to find it - can try system restore back to a date it was working and hope that system restore removes the program(s) in question. Which is never a guarantee.

I didn't have any luck with the exact wording either. The resetlog file didn't look "right". I found the KB at MS and it was worded a bit different. Ran that and the resetlog file was full of entries.

Will try that.

Nothing is wrong with the NIC. It works in Safe Mode and things like PING work in normal mode. I haven't tried the wired connection but the owner said he tried both wired and wireless and got same problem. IPv6 is already disabled (not installed).

'netsh dump'

Interesting to whom ? I piped it's results to a logfile and read through it and nothing glaringly wrong jumps out (to me).

'netdiag /test:winsock'

command not found

Another "Automatic Update" got downloaded too. What protocol do those use ?

I also thought it could be something wrong with the user's account seeing as no 'net works when logged in as them but does as admin. So I created a 2nd user, with admin rights, and logged in. Still no 'net access though.

Since I can PING websites, networking isn't broken. I can PING them by name, so DNS is good.

When I try »/ in a browser address, I get the same blank page. Interestingly, it takes a couple of seconds as if it's trying. Something is blocking the outbound HTTP port(s), yes ??

If you can get SUPERAntiSpyware on there that could probably fix it. There is a "Repairs" tab in the preferences section also called control center that can repair broken network connections [WinSock LSP Chain]. There are other system repair options in there as well like reset URL prefixes.

I'm not sure if this is related but I'm using Alltel wireless here and I'm having the same problems and My father who uses Alltel also is having the same issues as the OP.

I'm able to browse to some web pages, others not. I have tried an alternate DNS and same thing. I have Chrome, IE8 and Firefox.

They all do the same, either time out or partial load and they spin away trying to load the rest of the page. Ping is the same goes out and returns no problem.

has me baffled too.

I missed the part where you followed through on resetting winsock. Likely, nothing interesting to be seen. I was interested in IP/IPSec routing, transports, and proxies. You've tried:

netsh winsock reset
netsh int ip reset reset.log
 
right?

May as well complete the trifecta:
netsh firewall reset
 
Then enable logging (advanced tab on the FW dialog) and see what you can see in %systemroot%\Pfirewall.log.

Back to winsock. A system service (hidden, injected, or sitting in plain sight) could be adding to the catalog after reset. Try
netsh winsock show catalog >xsp.txt
 
An obvious sign would be the presence of something removed by the reset (check the reset log Edit: no reset log is generated for winsock - use a clean machine's catalog or Google and a fine tooth comb). Resetting winsock removed non-default Layered Service Provider registry keys. Unless one of the third-party repair tools claims to do more they're not going to help.

Sorry about the second one. netdiag is part of the support tools package (on the CD and a free download) but now that I've read all the steps you have and have not taken I see it's pointless.

AU uses BITS. BITS uses HTTP and HTTPS to transfer files. Another tool in the support tools package, bitsadmin.exe, will allow you to create jobs, add files to a job, and monitor progress. There's also a BITS MMC snap-in if you want a GUI but I don't know which editions, if any, have it installed. Never used it.

The presence of successful MS Automatic Update downloads means HTTP transport is working for the Update Agent but I'm fuzzy on the circumstances. Have any of these downloads occurred in Normal mode or were they all in Safe/Clean Boot modes? If I've read what you've reported clearly, ICMP (Ping) and UDP (DNS) seem unaffected.

The next thing that pops into my head is Group Policy restrictions. GPResult.exe might help. Myself, I'd probably have Process Explorer and NetMon running at this point as well as a copious supply of "Admin fuel" aka beer.

Will try the add'l 'netsh' commands you suggest.

As for the AU downloads, it seems to me that they're occurring while the PC is sitting at the login/welcome screen. It can be there for a long time. I'm working on this thing off and on (more off than on, mind you !). Also goes along with why I thought it was something related to the user's profile since 'net access (HTTP) works in Safe Mode.

I did try "Run as..." and signing in as admin but that's not allowed on XP Home it seems.

What would one look for in that log file ? All it contains (after attempting to access the 'net) is a bunch of "OPEN" and "DROP" UDP connections and they're all from "internal" IP addresses, i.e. 192.168.1.x addresses. Actually, since I launch the web browser -- wait, the XP firewall doesn't block outgoing connections anyway, does it ? -- the firewall shouldn't interfere.

When booting normally?

Auto-login / login that seems slow or Hall is busy and it can wait?

Only in Safe mode (blank default password).

We're looking for something specific...and we'll know it when we see it :D. XP SP2+ has a stateful firewall that does not block outbound traffic but we can use it to help troubleshoot the network stack.

OPEN, good.
DROP, good, if the RECEIVE flag is shown. Probably port 1900?
UDP only, bad.

We should be seeing TCP connection OPENs when you attempt to access the Internet. Sorry that I forgot to mention this but did you check both logging options (dropped and successful)? If so, we've almost confirmed TCP protocol IP stream sockets aren't making it to the firewall. If that's not the case we'll move on to WinHTTP.

Could you try FTP or POP or SMTP or all three, then check the firewall log again? You said FTP didn't work but I'd like to confirm the lack of TCP entries in the log.

Afterwards,

netsh interface ip show tcpstats
 
Oddities like zero's, much > than zero for In Errors, Out Resets equaling or approaching Out Segments?

If netsh complains about the Routing and Remote Access Service you'll probably have to change the service startup mode from disabled to manual before you can start it.

When there was only (1) account on the machine, it logged in automatically. At one point I added a "test" user account so when it boots, it stops at the Welcome screen.

Let me stop the logging and get a fresh logfile to look at. Once I initiate it, I will attempt to access the internet with a browser and take a snapshot of the logfile at that point.

The firewall logfile is attached. I actually cleared the logfile, restarted the firewall, and had to leave the PC.

.122 is the laptop itself. .50 is my PC. .104 is probably my wife's laptop.

The UDP DROPs are just NetBIOS/SMB broadcasts and a few DHCP packets. Could you lather, rinse, repeat for FTP? I'd like to verify, via the log, that it's not just HTTP running over TCP that's blocked. All we're doing is proving the earlier assertions of a third-party component forcibly knocking all TCP connections down.

tcpstats;
I'm trying not to look at the obvious correlations and stick to RFC definitions but, well, eew. It looks like an ornery LSP where there shouldn't be one (or firewall hook, filter hook, intermediate NDIS driver ). I'll get back to those once the FTP test confirms it's TCP in general and not just HTTP but that's looking like a formality at this point.

Will try FTP in a few minutes.

Remember, this still occurs when I disable XP's firewall so that leaves "filter hook" and "intermediate NDIS driver" from your list.

Doesn't one of the 'netsh' commands wipe out LSPs and make things start over ?

Well, the laptop's owner asked for it back at this point.... I enjoyed the challenge !

I did tell him if/when he takes it to someone else to "fix" to not let them simply wipe it clean and start over because that's what how too many people "fix" PC problems. If that's the solution, he can do that himself vs pay someone to stick a disc in it, reboot, answer a few prompts and walk away.

Thanks to everyone for their help.

I didn't think of this till first thing this morning. Not sure if would even work. Did you ever try removing all networking components and rebooting? Not that it matters now but I remember a similar problem years back with XP and it fixed it.

Yeah, I thought of that too but the stubborn part of me said "no, don't bother ... the NICs are able to ping, auto-updates was working and everything worked just fine in Safe Mode". Didn't do it obviously

I saw it suggested earlier in the thread. When you declined to do so, I figured you had decided to go the distance.

*sniffle* I was curious.

Hey there -

I was troubleshooting a friend's netbook with the same problem when I stumbled on this page. I just signed up to post this, so pardon me if I botch the HTML.

That case turned out to be an incomplete Norton uninstallation. To check that, see if booting it in Safe Mode with Networking helps. If it does, get the Norton removal program and run it.

Cheers!

Interesting.... He had Symantec AV on there and said it wouldn't uninstall (properly). I thought I sent him a link to Symantec's stand-alone uninstaller but don't know if it was done.

Just solved an identical issue on a friends laptop.
I've found a strange mix of AVG and bitdefender firewall registry entries.
After a Registry cleanup and a Panda AV scan and Firewall correctly configured, everything seems to work just fine

Those two "fixes" solved the problem ! I used Symantec's clean-up tool (ironic that their "uninstall" routine doesn't do the job properly) and then did a registry clean-up. Running the Norton tool and rebooting wasn't sufficient. Apparently there was still stray Norton crap left behind....
