Manager can connect through wireless but not through any browser

A Manager has an XP system and uses Verizon Wireless to connect to the Internet and get company e-mail.  He can connect fine but none of his webpages will display anything.  He can ping websites, we can see his computer remotely but none of his browsers will display a page.  The browsers are IE, Firefox and putting in IPs into the browser do not display anything either.  We cannot have him download of run a Winsocket fix because he cannot get to any webpage.  Any help offered would be greatly appreciated.

Hello regsamp,

Download this script on another computer and copy it to the problem computer. The script reinstall winsock, TCP/IP stack, and HOSTS file.

Hope this helps!

Maybe it is due to Internet proxy setting?

Worried about phishing attacks?

90% of attacks start with a phish. It’s critical that IT admins and MSSPs have the right security in place to protect their end users from these phishing attacks. Check out our latest feature brief for tips and tricks to keep your employees off a hackers line!

I will have to try the laptop when the Manager gets back because I can no longer connect and VNC will not allow file transfer either but I will try it and then post results.

Right-click My Network Places, choose Properties, then in the pane on the left of Network Connections choose Change Windows Firewall settings. Punch the Off (not recommended) radio button and OK back out. If the manager's notebook is using a 2nd party firewall,  disable that.

If that's not doing it, then I concur with psychic_zero.

Have the manager go into Control Panel->Internet Options, on the Connections tab, click the LAN Settings button and ensure all 3 boxes in that dialog are UNchecked. Then see if Internet Explorer will connect to the internet through the wireless.

I would dump VZAccess, too, and just have it dial #777 manually, but that's another subject (the 'new connection wizard' with no other way to add a new connectoid is one of the worst 'features' microsoft foisted on XP users. In my honest opinion).

The Microsoft firewall was off but the compute just had AVG put on and that prevented the browsers from working?  Will check the LAN Settings and post back.

AVG antivirus would not prevent browsers from accessing the internet.  But AVG can come with a firewall.  Then the AVG firewall can stop browsers from accessing the internet if not configure correctly.

Do not think it is AVG because it was on the computer for a week and it never did this but just speculating at this point.

Antivirus program can interfere with browsers, but AVG has not been known to do so.  If you had said you had Norton AV, then I would say for use the problem was the antivirus.

Got the system, turned it on and it is now fine.  Next step(s)?

Make sure you are in the same environment as the Manager when he failed to browse.  Wireless connection can be tricky.  There may be interference in Manager's office.

Can't really do that as they were in another part of the state.

They did not have a problem from the same location two weeks ago but I know how wireless connections can be volatile.

What is strange was as soon as I turned on the system, an Adobe Acrobat update was finishing and then everything worked.  I did not see this update when I had a remote connection to the machine earlier.  Maybe Adobe caused it.  I am scanning now.

The problem has not happened again.  It must have been something with the environment.  Thanks for the help.
