Cannot connect to external websites on xp sp 3 computer

Really need your help on this one, experts...
I have a Windows XP laptop (SP3) that i cannot get to connect to any external website. When I type in a URL the status bar on the bottom goes to "waiting for http://www.thewebsitename.com" and then eventually times out with an Internet error of "The address is not valid" or something similar.

troubleshooting steps i have taken: installed mozilla firefox and get the same time outs, tried a different profile and get the same timeouts,  i was able to install malwarebytes and ran a scan (could not update it because it couldn't connect) and it found a browser hijack program which i removed from the system and i still had the same issues. i checked the hosts file and there is nothing in there. I reset Internet explorer back to the defaults and still same issue. i put a different static IP address on the computer and still have the same issues.
As I am writing this i was able to get a titleblock (bar across the top that has the webaddress) to download, but the site eventually timed out.

I am completely stumped and i was hoping you guys who are smarter would be able to help me out. Thank you!

Since you are using a static IP address (yikes), I would suggest that you ensure DNS servers are setup correctly, WINS servers, subnet mask, etc etc etc.  Also make sure that you have correct proxy settings in Internet Explorer.  By default, Firefox will use all the same settings that IE is using to connect.  

That's a start...  hope that helps with the troubleshooting.

Have you tried a system restore?

If the computer is connected to a network are you able to ping different addresses (internal and external)?


I would check the dns settings, make sure they are valid.
Are they internal dns or isp dns?
If valid and working;
Flush the dns cache;  at command promt type: ipconfig /flushdns

i only added a static to ensure that there wasn't an issue with the ip that it was leased. I have since went back to dhcp address. i haven't tried a system restore...was trying to avoid that since this laptop is offsite.

In your case, first I would look for is a software problem or a comunication problem, I mean, are you conected to internet (emails, messenger, or just a ping). If you do, then, have you installed a new firewall or antivirus program??

Did you check the proxy settings in Internet options?

do any of your internet related applications work?  For example, Outlook etc?  You say you installed Mozilla and MalwareBytes...did you download them locally or transfer them via usb drive?

This may sound weird, but go to your device manager and tell me if you've got some oddly named network adapters in there.

bigbunk390, i double checked the dns settings and they are valid. i went ahead and flushed the cache and i still got the same issue. one thing of note, the main user of the laptop is unable to get into the LAN settings in internet explorer. Says that it is locked out by administrator, but we don't have any policies enabled to block those settings. it is not blocked for me when i log in though (i am a domain admin).

biaxis, no new antivirus or firewalls. i even have the windows firewall off. all internal stuff is working, but external sites are not.

dexIT, clarification....i am able to get into the settings under my profile and everything is right, but i am still timing out. under the main users, i cannot get to it.

group policy may be blocking the seetings if you can't see them

dexITCommented:
BGD302, I don't understand what you are trying to say.

Are you stopping the browser from attempting to connect by hitting the stop? And then verifying the lan/proxy settings?

dexITCommented:
OK, "everything is right" does that mean that the proxy settings are unchecked or checked?

snafumasterDirector of Information TechnologyCommented:
maybe try tracert from the command line and find where specifically it is haging

ggefterCommented:
can u ping the websites sucesfully? if so ... malware bytes should still grab updates. But definately sounds like virus/spyware.

log into safemode with networking and scan pc again, reset ip stack, reset all your IE settings back to default and make sure your proxy settings are Off, obtain LAN settings auto

dexIT, the proxy is unchecked under my profile.

ggefter, stupid question...when you say "reset ip stack" do you mean uninstall/reinstall IP?

cmd
At the command prompt, copy and paste (or type) the following command and then press ENTER:
netsh int ip reset c:\resetlog.txt

i may have found something that may be the issue. I found this entry in the windows system log:

"tcp ip has reached the security limit imposed on the number of concurrent tcp connect attempts"

I am researching...

Guys, thank you so much for all the suggestions. I figured out what the issue was. The above entry in the windows system log took me to this site:
http://www.speedguide.net/read_articles.php?id=1497

I applied the patch referenced on this site and i was able to get to all external websites with no issues.

Thank you again for all the suggestions.
