i got a big problem on a server 2003 x64 standart
its a root server in a rz on wich runs a gameserver
if we disconnect (not log out) from remotedesktop
the server freezes for ~20 seconds
the gameserver and the root server
but on connecting everything runs great ...
is there any known reason for it?

if we connect on 2 remotedesktops and disconnect one of them
we can se on taskmanager that nothing is happened...
but the server frezzes for 20 sec
