Exchange ActiveSync HTTP status code 409

I have started having major ActiveSync issures with all our Smart Phones, iphones, droid, HTC, etc. I have followed all the advice that I could fine here on EE. I even printed out an article by alanhardisty and followed it to the letter. it worked for about 30 minutes and then error messages 3014 and 3005, warning 3007 listed below start piling up in the event logs and users cannot connect. If I restart the exchange system attendant or dismount and remount the store it works for about 30 minutes then back to square one. Every user starts getting theese errors. I have not other clue as what to do here are the event ID logs:

I have patched, restarted, deleted and recreated. The exchange server had Viper installed and I uninstalled the exchange add in. I added exceptions for just about everything. I am at the point just to try and remove the AV and see what that does. everything was working fine up until a couple weeks ago then everyone stopped. We are using the standard version of Exchange 2003 and server 2003 enterprise. Any assistance would be greatly appreciated.

Thanks
