Okay – Another update. I have found a temporary work-a-round. Going back to the one time when I did get re-connected after disabling / enabling my network card, I tinkered with that and found that I can get back online if:
1) I have Jitsi running when I first disable the network card in device manager (Jitsi quickly reports network connectivity lost)
2) I re-enable my network card and within a two second window try to get Jitsi online.
This seems to work for me 80% of the time. And I have no idea as to why. It smacks of firewall problems to me, but I have already gone over that and don’t wish to completely un-install it and see if Jitsi will work.
Or possibly a failing network card? Everything else works just fine, and once I get Jitsi connected, that too runs with no problems. I can go offline with one account, and as long as my other account is still online, I can get both online. If I go off line with both accounts – Jitsi goes back to the unable to connect thing until I disable/re-enable the network card thing again.
Annoying but hey ho – At least things are kind of moving again

John- I used tcoffin@jit.si and my password. I was the one who confused you because I don't know what the hell I'm talking about. I was referencing, best I could, what the jit.si registration process was telling me..."Unknown XMPP error (jid-malformed(400)). Verify that the server name is correct". At this point I had no idea what to do as i simply assumed Google was my server. jit.si then asked me to choose a different server from a list in a 'drop box'. When I brought up the drop box there were no other servers listed from which to choose, nor a way to input anything...dead end.

What did you use in the XMPP username field, I used jervin@jit.si and the account password. and it seems to have worked although I'm not sure what XMPP is used for. I just use jitsi mostly as a sip softphone client to communicate through my Asterisk/FreePBX phone system. By the way, I was confused about the difference between what I meant by jitsi (software) and what you meant by jit.si (a server address).

John- I'm sorry, I'm not sure what 'server' I have. I use google. When you mention a "direct SIP URL's" I have no idea what you are talking about. I am completely clueless about computers and the nomenclature thereof. All I know is that I downloaded jit.si, registered and then when I tried to complete my registration a window popped up and said "Unknown XMPP error (jid-malformed(400)). Verify that the server name is correct". I was now out of my element.
Unfortunately, I need jit.si for business and have to try and figure out a solution.

Yes, just jit.si is the problem. Can't get to their server.

And you can do other network functions like email and web browsing successfully from that machine, pinging and external address (like ping.symantec.com). It's only Jitsi with the problem? Cables test OK too I suppose.

Well I seem to be stuck for now. I had one temporary successful login after I disabled then re-enabled my network card via device manager. Thinking I might have solved the issue, I logged out of Jitis, shut it down and re-started it - and was back at square one with the no connection problem. I re-created the steps I took but now they have no effect.
Other things I have tried:
Disabling firewall / AV protection. No effect.
Checked windows firewall was still disabled (My AV normally keeps it off) - Still disabled.
Disabled all other virtual network devices except for my LAN card - no effect.
Emil, you did ask me if I had disabled the parallel DNS resolver - Nope, I hadn't. Curiously though, I noticed that the failure to login popup messages appear straight after the main Jitsi window appears. I tried setting the length of time before the backup DNS resolver kicks in from 1,500ms to 2,000ms then 20,000mm - and it made no difference. The failure messages are still instant. Should that be correct? Jitsi takes about 4 to 5 seconds to start up from the click on the icon to when the main window appears (after the loading screen) - I would have thought with a 20 second wait before the backup DNS kicks in, there should be that length of pause before I get the error messages. It's like Jitsi is just skipping that feature altogether.
I have also tried setting the backup DNS resolver hostname to 8.8.4.4 and 8.8.8.8 but those have no effect either.
Any other ideas would be gratefully accepted

Thanks for the help Emil – I’ll look into that to see if somehow Jitsi is
trying to use the wrong network. The three local IP’s are my actual IP, one
generated for Hamachi and one that Oracle VM Box creates and uses. I had
shut both of these others down to make sure they weren’t interfering with
anything but still no luck. I guess I’ll continue to mess with it.
Just out of interest, I did try installing Jitsi onto my netbook and that
worked with no problems so I guess that points the finger of suspicion at my
PC. Damn weird for it to die overnight.
@ John Ervin : I’m running Java version 7 update 60, both for 32 and 64bit.
I just checked again and the java site still says that is the latest
version. No other older versions installed.
FWIW, Jitsi comes with its own Java version on windows so the version
of your own installation doesn't really matter.

Hey there,
You seem to be getting no DNS results for the XMPP servers your are
using. This could be a problem with your DNS server or with your network
settings. I don't see the parallel resolver kicking in. Have you
disabled it?
You seem to have three local IP addresses. You might want to check that
everything is OK with your routing.
Hope this helps,
Emil

Hello
I have been running Jitsi stable build 2.4.4997 x64 on my Windows 7 rig
for months with no problems. Last night I quit the program cleanly (went
off line then clicked ‘file’ and ‘quit’) then put my computer to sleep
(Saturday 15th June) as normal but when I resumed this morning (Sunday
16th June) I found that Jitis refused to connect to either of my two
XMPP accounts, saying ‘Connection failed’.
I have tried:
Rebooting PC. No effect.
Checking that Java was up to date (both 32bit and 64bit versions) – It
wasn’t
so I updated that, but I do check this quite often. Still not working.
Uninstalling Jitsi + deleting the files the uninstall leaves behind in the
Appdata/roaming/Jitsi and appdata/local/jitsi folders.
Re-installing the latest stable build Jitsi for windows (x64) via the
Jitsi
website, putting my accounts back in but to no avail. Still not
connecting.
Checking I could actually log in to my XMPP accounts via the web which
worked just fine.
Rebooted my router, still no luck. It might be worth me mentioning that I
also run jitsi (on a different account) via my Android phone which works
fine so I’m guessing that rules out internal network issues.
Uninstalling Jitsi + folders again.
Installed latest Jitsi nightly build 2.5 x86 (13-06-2014) – Same results.
Unable to connect.
Stroked my beard for a bit. Made a cuppa tea. Sat down and trawled through
the logs to see if anything obvious was being listed and noticed that
there
were a few errors about being unable to locate either of the two XMPP
servers, details below:

No server addresses found
Flushed my DNS via the command prompt (run as admin) ipconfig /flushdns
- Shutdown my PC, counted to 10 and restarted it. Still no joy.
So now I'm stuck. I've included the logs from both versions of Jitis
(stable and nightly) and can only hope you have a simple solution. There
were no other changes done to my computer that I'm aware of apart from
those I have listed.
I hope I've included enough information and await your enlightened
response
