Hello Sushil, In addition to Patrick's post, here is useful info for you. You need to mention source symbol path before analyzing dump file. Detailed snap shot is: Open Win debug tool go to file select source file path enter below path (*select your own drive path, in my case I chosen E drive) for more details please go through this link http://blogs.technet.com/b/askcore/archive/2008/11/01/how-to-debug-kernel-mode-blue-screen-crashes-for-beginners.aspx#3476888 Regards, Ravikumar P
