Are you saying that you renamed a Core Server that was already installed? This can break LANDesk completely. Please clarify what changes you made.
No I didnot change rename the core server, i have registerd the netbios name in the DNS to make it a FQDN. Then i have created webshare for the software distribution on the devices which are behind the gateway. software distribution works & inventory from the managed device works but after making http share for software & ldlogon folder i cannot do the inventory scan for the device from core server.
