I cant browse any sites either by name or ip. All my ip settings are correct. Im able to ping the default gateway and www.google.com. Im also unable to connect to my exchange server to retrieve email. The laptop is running xp pro and is on a domain. Using IE7 but have tried firefox with same results. All other machines on the domain using the same gateway are able to browse fine. Any ideas?
Bad NIC
Port disabled in switch room
Needs new IP but it wont release it
Just some thoughts off the top of my head
Im able to ping websites so your suggestions dont really make sense. Im also able to connect to the router config page using a browser.
Sorry I didn't read the it right I thought you said you couldn't. My bad
Have you run hijack this???
recently infected with something???
Anything in the event viewer??
Have an av or firewall running..???

Can you ping your DNS?
I've seen similar problems with AV firewalls like Symantic Client Security/ Symantic Internet Security, MCAFEE Firewall. The user is prompted too allow/block communication with that specific application (IE or FF) and they choose block because they're too click happy and don't read. This normally happens after an update... windows patch for IE or update to FF. The firewall detects a change in the program and has to recreate the rule.
Did you check to see that the browser communication was setup right? I've seen a case where the user checked off to use a proxy but didn't specify one. I've also seen where they've unchecked to use a proxy when a proxy was needed. We set ours up in group policy so they can't change that...
Could be blocked at your company firewall? A simple test for that would be to telnet to any website on port 80, etc. This would still allow you to ping/resolve but not connect.
MadBeaver: It would appear that all communication is working fine except for browsing. He is able to ping and resolve google.com and connect to the exchange server.
Everything is clean. Nothing in event viewer. Have disabled firewall but still same. Have also tried restoring to a previous restore point but still same.
What AV/Firewall are you using on the client? I've had problems after a program update with Symantec Internet Security. The symantec proxy service got screwed somewhere in the install. Uninstall/reinstall fixed it.
Sounds like a proxy or gateway issue. You sure you don't NEED a proxy to surf?
Check one of the other computers that works fine to see if they're using a proxy.
We've got similar issues at work. Once or twice a week, I've got to re-image a
W2K unit. The image is probably a year old now and was made when we had an
ISA server (gone now), complete with a proxy. After re-imaging, I've got to go
in and run the network wizard to get port 80 connected.
Speaking of which, try running "New Network Connection" in "Networking" in the "Control Panel". Might be worth a shot.
I will check the browser settings on another client to see if a proxy is in fact being used. Ive only started working for the company as their systems admin. This particular laptop is running mcafee personal firewall which i have disabled. Whats making me think its not a browsing problem is that we cant sync with the exchange server to download email. Ill try what has been suggested on monday but if any has any other suggestions please reply. Thanks again all.
I assume you've tried this all in safe mode too. But really, uninstall the Mcaffee, don't just disable it. Check for proxy settings in your IE. Uninstall the NIC.
Try a boot CD like knoppix.
Our company doesnt use a proxy. Have uninstalled/reinstalled the nic but still same. Have also uninstalled mcafee. I had a client last night who was experiencing a similar problem since upgrading live messenger: able to ping google.com but unable to browse. I tried a system restore, uninstalled messenger and eventually had to do a fresh install of windows to get it up and running. Any ideas?
As thierry101 suggests, "try a boot CD like knoppix". There's also
Bart PE. Sometimes there's problems with boot CD's picking up nics,
particularly with the newest computers. Boot CD's are an essential
admin tool.
Hijacked (redirects) HOSTS file.....or http://www.cexx.org/lspfix.htm :)
Ive tried repairing winsock2 and also running the tool suggested in the above post but still unable to browse. This is now happening on two laptops in the office. Any other suggestions before reinstalling? Thanks for all suggestions so far.
sounds like these laptops...travel outside your network...then come in infected with something...
Sometimes the easiest, quickest way to fix an issue is to format and reinstall....
sounds like what ever it is is spreading :eek7:

Are your servers configured to foward DNS requests? I'm just wondering if maybe on some slim chance that it's a domain related problem. If these laptops aren't connecting to the domain properly, maybe the DNS requests aren't getting fowarded properly.
I know that you're getting some resolution when you ping certain sites but, I'm wondering if an anomaly is allowing resolution for certain sites (an existing local cache)? Also, are your clients setup to automatically aquire a DNS server? If this is the case, have you tried to manually insert a known DNS server in your IP settings?
I dont think its a dnds problem. I have the dns addresses manually set in the ip settings and i am able to resolve names as well as ip addresses. I DO think its a winsock problem, however, all suggestions through here and google.com havent resolved the issue. I have found that an install over the current install also doesnt resolve the problem and the only way to get connectivity is to format/reinstall. Thanks all for the help, im just going to bite the bullet and format/reinstall.
Cheers
eh, I know its probably too late, but one thing I have seen with employee laptops that get used at home is they put their home ISP software on there. What I've found on at least 3 seperate laptops so far is that for some reason traces of the connection remain, especially when its dialup. Then, when you run IE its looking for the remains of the home connection, not finding it and jumping into offline mode, even if it is set to connect through a LAN. Solution was to delete ALL dial up connections.
Go to Run --> enter "netsh diag gui" with out the quotes. Click on "set scanning options" and make sure everything is checked (especially verbose). Now click on "scan your system".
Review the information under "Modems and Network Adapters".
Expand all of them and see if you have any "Failed" items.
If failed, what failed? Post it, PPPpost it so we can see.
Is the laptop Static or DHCP?
If Dynamic what is the IP addy?
Did you "JUST" plug it in to the network?
