Strange problem, Mom 2005 all working very well indeed. Changed to a new fixed IP address as I had overlooked it was DHCP originally, and I cannot load the operator console (error connecting to server : localhost) and the administrator console says failed to initialise snap-in. Mom service is running fine, I have reinstalled the user interfaces and repaired the installation. Nothing of consequence in the event viewer at all, in fact the web console is reporting fine.
