Questions about termination

Are there "neutral" ways for a graduate student leaving his graduateschool without completing a degree? Is a student voluntarily leaving his graduate school called termination?

When applying to another graduate school, will the student be askedif he has ever received a probation and termination? How will that affect the student's chance to be admitted to the new school? For example, hereceived a probation because he didn't manage to find a researchdirection and research advisor in 2.5 years, followed by a termination a few months later because he didn'tpass his PhD qualification exam without "protection" from an advisor?
