I have installed LMS on Windows 2003 server. And everything was going smoothly.
Recently I have found a problem like that, when I add a device, it shows in the DCR,
But when I try to add this device to a group for topology view it does not appear in the
desired groups and also in the topology map.
Please note that number of devices did not cross the license limit.
Required information putted in the Cisco devices and many times I added and deleted the same devices but the problem is same.
