COMMAND

    kernel (performance counters)

SYSTEMS AFFECTED

    WinNT

PROBLEM

    There's possible DoS in WinNT.  It deals with a memory leak and  a
    performance  degradation  when  invalid  performance  counters are
    invoked from another computer.

SOLUTION

    A post-SP5 hotfix (US) has been post:
