Windows XP forum: ThorConnWndClass & Outlook

ThorConnWndClass is an internal part of 'Crash Guard' Symantec have not included it in the latest Norton release, appartently it was a source of problems. Usually removing crash guard cured the TCWC problem. Did you remove it as one of the 'practical' solutions. If so that could have been the 'cure' not the deletion of the screensaver

i am having the same issue.. help.. i also do not have any symantec programs.
what did you do to fix if anything..?

I tried the Detect and Repair and now I am able to recieve and send mails again.
I refered to the advice below:

If I exit Outlook 2000 (OL2000) when it is sending email, too often it will not exit and you'll see it in the task manager. It won't run again until you endtask it.
The issue was fixed multiple times by Microsoft and still was noticed at the office in OL2002.

It appears to be what I call an endearing bug. I wish a screensaver was the cure for this one.

After losing a hard drive and after doing a full rebuild of windows 2000 Pro one of our users is now experiencing this problem too.

He is using Office 2003 suite.

I applied SP4 and all subsequent updates this morning.
I also installed our "subscribed" McAfee suite this moring as well.

When the user came in, he was able to get a few incoming e-mails but shortly thereafter Outlook stopped sending out e-mails, they seemed stuck in the outbox. We also could not get any response from the Internet (it couldn't get out to the outside world) Maybe this is why the outgoing e-mails stopped too.

So we tried shutting down and restarting but it came up with the ThorConnWndClass not responding thing.

When it finally rebooted Windows 2000 came up partway and we were left at a Solid Blue Screen (not the blue screen of death) with just a Mouse cursor arrow.

Powered off and rebooted and all was well at that point. Launched Outlook, E-mails still not being sent, no internet. Uninstalled McAfee rebooted and for now the system is happy again.

BTW the full rebuild was done with the supplied CD's from Gateway that had the "Free" Norton/Symantec AV software. Although we don't use it, I wonder if somehow the Thor thing got into the registry during the rebuild.

Like many of you I have been struggling with this problem for some time now. Finally I found something that worked.I tried System Mechanic V6 from Iolo. Brilliant. It took a lot of my patience to let the software scan and clean my laptop - like 3hrs plus. I clicked the ''PC Total care'' button. Now, my Outlook 2003 runs as it used to i.e updating with each msg sent. My Activsync for my PDA is like new again. My print spooler is back on line - It was fine on my other laptop. My hpq8tra printer error message has gone. My ThorConnWndClass error has gone. My laptop shuts done automatically in a few seconds when asked to do so and not in 10 minutes with manual intervention. I have seen some of the other msgs on this System Mechanic V6 software but for me it has meant I can get back to work and stop trying to be my own techy. I am self employed. It is the best bit of software I have used for AGES! It is far more than a registry cleaner. I don't know what it did exactly and I don't care. It is brilliant and it did what it said on the packet. Good enough for me. I am running XP Pro with SP2 +Zone Alarm full security Suite.
Hope that helps. Good luck.

So which one is true, what is the answer? Has anyone else tried system mechanic to repair this issue?

If you can not delete messages in outbox change auto send receive to off, close and restart outlook. You can now delete or move outbox messages to drafts. It locks up because it they are cued for send.

This issue remains. You can never be sure if Outlook 2000 to 2003 will really quit. As I'm now writing a Windows Mobile application with Visual Studio 2008 on Vista 32 with the latest Active Sync the basic machine has changed 3 times yet Outlook 2000 to 2003 still behaves like the Energizer Bunny.

Well the issue doesn't happen as often but its still there.

From my cohorts with Office 2007 they report the issue remains in Office 2007.

PS. My google email settings are correct.

Have you seen this thread? Not sure if it would help but the recommendations are different than what has been listed in this string so far. Best of luck.

Thanks for that quick fix! Not sure why it works but it does. I am also running Outlook 03 on XP on my laptop tied into my home system. It only just began happening in the last few days. It has worked fine for several years...go figure
