Thanks a lot Jan for your reply. I would really appreciate if you could find me the bug ID for this. I have already checked on boot navigator but still couldnt find any bug related to this issue?.

Just checked my mails, the issue was something with validating certificate signatures on executables, so on a file copy it would spike leventmgr.exe which is doing the actual validation. It was solved though in 6.0.1 already, so you are probably looking at another bug, you should open a TAC case i think. One thing you could check though is if you have many applications in you untrusted apps list on the client, this can result on alot of processing time used by leventmgr in my experience.

It could be this bug which was found in 6.0.2.126 and is not fixed:
