build ID: FF 20040522 on Win2k. Steps to reproduce: extremelely random, I've seen this issue multiple times for a few years and finally thought it could be a Mozilla issue, not a network issue, so I captured some logs. 1. Browse some website, news.bbc.co.uk then zdnet.com in my case, browser had been open for 2 hours, 2. At some point "host not found" shows up in Mozilla for an already visited site (in my case, I had visited news.bbc.co.uk a few minutes before getting host not found) Workaround: - either closing Mozilla, - waiting for a few seconds enables Mozilla to properly re-enable name resolution through DNS, - or starting IE, resolving news.bbc.co.uk, then going back to Mozilla, it would resolve properly too. I've seen this issue on 2 different Win2k machines. A sniffer shows a NetBIOS query is issue for news.bbc.co.uk (instead of DNS), not sure why, corrupted cache, DNS resolver cache, Mozilla not setting some "flags" ? I initiated a discussion on this on n.p.m.netlib.

I left the log intentionally 'large' (500K) as there may be interesting data before the issue actually happen. The end of log corresponds to "Host not found" message being displayed and Ethereal capturing the log (I then closed the browser). I still have the initial log (45MB) if some data is relevant.

This log was produced with FF 20040602 Win2k, after 20 min. of browsing, the original log is 15MB large, I only attached the relevant log starting with failure to resolve gamespy.com and zophar.net. Was browsing http://codeblogs.ximian.com/blogs/evolution/ and http://www.gamespot.com/features/6089278/index.html when I loaded a bookmark pointing to http://www.gamespy.com/articles/?constraint.grid.section=Hall+of+Fame and loaded www.zophar.net manually in second tab. I understand this is random but this may help understanding the DNS requests in the log file. As soon as I started these 2 requests, they anormally took a while and I got the dialog "Host not found" on both. I immediately tried again, same result, 30 seconds later, it worked and resolved fine (I left the last 3 successful seconds before closing FF, so this shows up at the end of the log). Note: Ethereal wasn't opened at this time but I assume these host resolving requests went through NetBIOS again.

It still happen for every day. An example today, Firefox stopped resolving for 20 seconds, as soon as I started another application using TCP/IP, XChat to connect to irc.mozilla.org, then Firefox could resolve properly again (same session and host names), being "unlocked". Ben, Darin, any idea ?

Sounds like an OS problem to me.

reasons why I filed this bug report: - whenever you start another application, it automagically work again in Mozilla, - it seems to be totally random, - only seen this in Mozilla, not other IP applications: IE, etc. then again, if you think (from the logs) it's an OS issue, I'm switching laptops in a few weeks, will see if this issue still happen or if it's Win2k slowly dying after 3 years of intensive usage. :)

New laptop T40 Win2k doesn't seem to exhibit this issue anymore using FF trunk 0.9+.
