Markus Jansson, Registry Question.

hi, i am going through the Markus Jansson site and it says to delete the NullSessionPipes and NullSessionShares keys found at:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanManServer\Parameters\NullSession Pipes\

does he mean here instead?
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanManServer\Parameters\

it's about 1/4 down the page, just above Enable Windows XP internet connection firewall (ICF)
