Browsers fail - trying to check everything.

[jmair]

I have a client that fails instantly when connecting to any intranet or internet based website. Instantly, the browsers display "This page can't be displayed" (IE) or "This page is not available" (Chrome).

 

Here is what I do know.

• Ipconfig /all - is fine.

• No proxy setup in IE or Chrome

• Tracert to google.com goes beyond our isp.

• Can ping 8.8.8.8 fine.

• Capable of network activity.

• No IP conflict (static ip, nothing else shares the ip)

• Dns service is working (able to nslookup msn.com and resolve an ip)

• Browsers fail instantly, even after resetting all settings to default.

• Can not display even an intranet based page via ip.

 

Any other ideas on where to look that would be stopping these browsers instantly?

Occasionally one or two of our stations are connected to ports intended for printers. These stations allow users to logon, open Word etc and create, edit and save documents. What users cannot do when connected to printer ports, on the printing VLAN, is browse any websites.

 

Not sure about the other tests you outlined in your post as when this happens we usually switch the ports back and everything returns to normal.

 

HTH.

Brilliant thought DaveP, I wouldn't never have thought of that. Removing printers didn't resolve the issue though. I've installed IIS on the machine and can access localhost:80 (the default iis splash page). Still can't view anything else though.

What you need to do to try DaveP's suggestion is to plug the network cable into one where another PC can get 'net access.

Or plug another device like a known working laptop into the network socket where this failing client is currently.

Vikpaw, the machine has a second nic and I tried a different jack to that second nic and same result. I've been doing a virus scan for a few hours (28% in).

That's changing too many variables at once!

Use the same nic, same cable but a working port elsewhere. Or is that what you meant?

Scan is a good call, could be malware or a browser hijack gone wrong.

You could try something like portable Firefox...
