Why no columns "cpu","disk","procs", "svcs" displayed for Windows 2003 clients on web page of hobbit server?

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.

Regards, Case
