123860 - DNS lookup fails & says "The connection was refused when attempting to contact xxx"

Status: VERIFIED INVALID

(Core :: Networking, defect)

Description

[Keith Felt]

Build: 2002020603
Win 2000, SP2

- Load Mozilla
- It attempts to load the homepage http://www.mozilla.org/start, 
says "Resolving host www.mozilla.org", times out and then displays the alert 
message "The connection was refused when attempting to contact www.mozilla.org."

The same thing happens with all URLs.

DNS services are working nicely for other applications on the machine.
No firewall or proxy in place.

netstat -a reports no http connections during this whole process.

The problem appeared with 0.9.8. 0.9.7 worked well.

[Matthias Versen [:Matti]]

Reporter:
Have you installed Mozilla over an older build ?
Can you try a new profile ? (run "mozilla -profilemanager")

Comment 2

[Keith Felt]

Uninstalled 0.9.7 and checked that all files and registry keys had been removed 
before installing 0.9.8.

I've run 'mozilla -profilemanager' and removed the existing profile, and then 
created a new profile.  Same problem appears immediately.

After the initial timeout and the "connection was refused when attempting to 
contact www.mozilla.org" alert has appeared, subsequent attempts to load any 
URL cause the alert box to pop up immediately, no timeout or delay.

Comment 3

[Matthias Versen [:Matti]]

Do you use (or used in the past) a firewall like Adguard, Zonealarm ?

If not:
Can you generate a HTTP log ?

you can define these environment variables:

  set NSPR_LOG_MODULES=nsHttp:5
  set NSPR_LOG_FILE=c:\http.log

you can set these in the control panel, under system->environment, or you can
set these in a DOS box and run mozilla from there.

Comment 4

[Keith Felt]

Set the above environment variables and launched Mozilla.  It gave the 
usual "The connection was refused when attempting to contact www.mozilla.org" 
message.  I then tried accessing www.google.com.  So both are in the http log:

Did you install via a proxy?

The installer may have contaminated your "default/prefs", which would force
proxy settings into all new profiles.

Check your proxy settings, in most cases(but not all), your proxy mode will
display correctly while you are running. If not, you should search your drive
for the presence of a file called "all-proxy.js"

[Keith Felt]

After doing some more checking, the ZoneAlarm firewall product had been
partially disabled, but some pieces were still installed.  Uninstalling
Zonealarm has resolved the issue and 0.9.9 is running nicely.

Suspect that since the front-end for ZoneAlarm was not running, new programs
could not be added to its list of "approved" programs.  Thus Mozilla 0.9.7 was
on the list and worked, however 0.9.8 and other builds would not work.

My sincere apologies for taking your time.  Please consider this bug closed.
Thanks.

that's a known Zonealarm problem !
(Adguard or Tinyfirewall is better..)
