visual studio .net debugging: Hi all

My application has a problem which occurs rarely(kernel32!
RaiseException+0x53 ), to explain about this i need to tell about my
appln.

It is an kiosk application, and the problem occurs only when i reboot
my machine once a day,and the application is a big multithreaded
application too.To debug this i have attached Adplus to my production
site machine and got the crash dump too.I started analyzing it and
need a bit of help in it.Please go through the dumps and help me with
the same.

This is my 1 st chance exception analysis
