Hello, Sorry if the question was allready asked, but i havent found anything on it. I installed OMSA (Server Administrator 5.2.0) on PowerEdge 2850/2650 servers (Windows 2K and 2003 server) and IT assistant 8.0.1 on an other server (Windows 2k). When i try to discover network, the servers appear on MyRoot-Unknown category on the left tree of the application and some of them don't show any informations (only IP adress). Maybe i need to install a Agent on them or something like that ? Im lost on all the Dell OpenManage applications :) Thank for your help, Bibop993
