Centralized bbwin hobbit-clients not working for proc and ports

I'm trying to configure monitoring for windows servers so that I get alerts when ports such as 80 and 443 are not available. I understand that I have to set the servers to central mode and have done so on 1 client server for a test as below.

<!-- bbwin mode local or central --> <setting name="mode" value="central" /> <setting name="configclass" value="win32" />

My hobbit-client.cfg file has the following:

HOST=xxxxx.co.uk

        PROC BBWin.exe 1

        PORT "LOCAL=%(:80|:443)" state=LISTEN TEXT=http and https

Unfortunately this is not working! I get white entries on the main status page with "No process to check" for proc and just a "-" for ports. I am getting the "Client Data" available for proc with current date and time, but the status of the actual page is reading as last updated back in November when I first changed the bbwin mode.

Any ideas where I am going wrong?

(We have a solaris server being monitored from the same box and using the same config file and both proc and ports are working fine for this.)

Thanks,

John
