I have usually relied on the STOP error and a google search to determine the cause of a crash... but I know I can open the .dmp file generated and examine that for probably more thorough information. Can anyone tell me what software will open this file? I have access to TechNet and MSDN, so I think I should be able to get my hands on the appropriate tool... I just don't know what that tool is, so I guess that's the question - what's the tool??
