Hello Donald, I know this isn't an answer to your question, but for the most part most SCOM implementors disable STT's out of the box. However, maybe someone has a sucessful story on using STT monitors and can provide you with some insight.Regards, Blake Email: mengotto<at>hotmail.com Blog: http://discussitnow.wordpress.com/
