The performance counters on the machine get corrupt over time and can be rebuilt using the following command line argument:
lodctr /R
The command must be executed with administrator rights, otherwise an error code of 5 is returned.
The command may fail with an error code of 2 and this should be remedied by executing this command "attrib -a -h -r -s c:\windows\system32\*.*" followed by "lodctr /R" again.
The machine must be restarted after the command is successful in order for the changes to take effect.
