I'll have to do some research to get all the info you have in your footer. The only other program was Zone Alarm, I disabled that and nothing changed. I've updated all my drivers, my next step is uninstalling Microsoft Security and re-installing. The thing that I don't understand is what the heck changed to make this happen all of a sudden?

Oh ZoneAlarm and MS security essentials at the same time, well that may explain it.
I in fact run ZoneAlarm quite happily, I can give advise on configuration tomorrow (I've got it optimized for Sonar), in the meantime could you please go to ZoneAlarm -> Help -> About -> Copy to Clipboard and paste here please.
Make sure you remove your serial number though!!
 
If it's expired let me know... BTW you might think you've disabled ZoneAlarm but you haven't (impossible without removal).
Then we can decide on best course of action...
 
Cheers...

ZoneAlarm ForceField Spyware Sites Database: 04.155
 
I'm using the free version obviously

Sorry what's the windows version and version of Sonar? (64 bit or 32 bit?).
Trying to work out best option for ZoneAlarm, depending on the OS. Might need total removal.

Windows 7 home premium Sonar Producer x3c 64 bit

OK so the Free version of ZoneAlarm is next to useless, it does not do antivirus and frankly the only version that's any good is the internet security suite or extreme edition.

Windows 7 firewall and security essentials should be perfectly adequete unless you wish to buy ZoneAlarm (I run the paid version myself without issue, this is not necessarily a recommendation as there are other good paid for virus scanners out there).


Assuming you don't want to buy ZoneAlarm here are the steps I recommend:

1) Remove ZoneAlarm. Reboot.
2) Remove Windows Security Essentials. Reboot
3) Install Windows Windows Security Essentials. Reboot.

4) Make sure windows firewall is turned on:

5) Run windows update (several times if necessary). Install optional performance updates as well. Reboot.
6) Do a full virus scan of your hard drive with Security Essentials.

7) Run chkdsk on your harddrives (if you haven't already).
8) Check your event log again.
 
If the situation persists after this we will move onto driver updates.
Time for bed!

Thanks for all your help first of all. I've completed all the above steps up to full virus scan. Removing ZoneAlarm had no effect on the problem, but hey, if it's 1 less useless program I'm running, so much the better. I'm now running the full virus scan...looks like it's gonna be awhile, I'll check in later with the results.

Full virus scan. No problems. No success. Drivers all updated, all steps above you suggested completed. Sent .dmp files to Cakewalk. Guess we'll have to see what they come up with.

I called cakewalk today, and spoke to a tech in less than 10 min...hasn't solved anything yet, did some tweaks, asked questions and gave info etc, But I got a ticket going, and I was emailed some tech tip on my mixing desk, and win 7 tweaks to help try to nail down the problem....
 
I think you should Give them a call....turn of all security and firewalls...is what I suggest.
check out the post about win 7 tweaks I posted...if you want to try it.

I saw in a couple of web threads that deleting/renaming one file seemed to clear it up for some folks.
 
Might be worth trying.
 
Here is the snippet from one of the threads:
 
"Problem 2: “Microsoft Security Client OOBE” stopped due to the following error: 0xC000000D
It looks like this is caused by some kind of corruption in the AV Client, anyways simply rename the following file and reboot:
C:\ProgramData\Microsoft\Microsoft Security Client\Support\EppOobe.etl (add .old or something)
Fixed!"
 
Please note that the above path is in a hidden folder (ProgramData), so you might need to enable viewing of hidden folders.
 
Hope that works for you,
