Just had a very irritating problem at work. Since I changed my corporate windows network password (it’s a must on regular basis) I need to use the new password for web browser proxy servers. AFAIK the Google Chrome browser was asking for credentials when I installed it. I probably checked “save password” because it never shows up again. Now after changing my windows password Google Chrome wouldnt work – it just shows “This webpage is not available.” for every page or tab. I tried disabling/enabling proxy, used “chrome://net-internals/#tests” to check whats wrong and in the EVENTS section i found that PROXY_AUTH was returning “Access Denied” so I knew it was the new password that didn’t work. After long trial&error tinkering and googling, this is what worked for me:
1. for the Google Chrome shortcut Right-Click (in Windows) and click Properties.
2. Find the Target section (it should end with ..chrome.exe” )
3. append to Target: “–proxy-server=PROXY-SERVER-IP:PORT”
4. it should end like this: \Google\Chrome\Application\chrome.exe” “–proxy-server=10.10.2.2:3128″ (example ip)
Thats it! Worked for me, it even didn’t ask for the new password!
P.S. My blog had some malware in the wordpress installation so it was blocked for some time.
