Hobbit server 4.2.0 running on RHEL4, BB client 1.08d on Windows 2003 servers. 

There're no such columns displayed , e.g. "cpu","disk","procs","svcs" for Windows 2003 (servers) clients. Only three columns, or "conn", "info","trends" displayed. no firewall between them.

Some parameters dismatched? connection parameters on client are default as below:
IP Port:1984, Timer:300,Logs Timer:60

But one Windows XP client looks like ok, almost same parameters.

Any suggestion will'be appreciated.
