I've noticed that when I do an sp_who2 during times when my server is running slow, I see multiple entries for...

Program Name: PKM
Login: NT AUTHORITY\SYSTEM
DBName: master

We don't have an application called PKM and I suspect it's generated by SQLServer or the operating system. I've not been able to find any information about it.

Anybody have a clue?
