Don't ever deactivate the CCM service via Service Activation unless you are permanently removing a subscriber from the cluster or turning it off on the publisher for good.<div><br class="webkit-block-placeholder"></div><div>As Lelio saw when you do this you lose all service parameters for the server. Also when you re-activate the service the server gets a new CTI node ID. This means that the CCM service on all other nodes in the cluster will have to be restarted before they pick up this change, ie no SDL links to this server. The last big thing de-activation does is remove the server from all CM groups it is in. </div><div><br class="webkit-block-placeholder"></div><div>Stopping/Starting/Disabling the service via the Win2k services.msc doesn't hurt anything and if you need to prevent CCM from starting automatically set it to Manual or Disabled there. </div><div><br class="webkit-block-placeholder"></div><div><div><p style="margin: 0.0px 0.0px 0.0px 0.0px"><font face="Helvetica" size="3" style="font: 12.0px Helvetica">-Ryan</font></p> </div><br><div><div>On Jan 9, 2008, at 9:10 AM, Lelio Fulgenzi wrote:</div><br class="Apple-interchange-newline"><span class="Apple-style-span" style="border-collapse: separate;
