How to stop replication that already running

Hi All,

is there any way to manually stop replication that already running.

i already running replication but it seems that i forget to unchecked the package replication so it makes my NS very heavy.

i use i tier hierarchy, 1 NS for central and 1 NS for Site branch.

my total client that connect to NS is 24.000 node.

thanks

Efendy
