Newby alert: WMI in other network segment

Hi,

I'm totally new to spiceworks and so far, I like it ;-)

My detection quota is very poor, since most of the computers are located in another network segment attached via a fritzbox to fritzbox vpn.

So the topology is

192.168.2.0 Frtzboxes 192.168.10.0

The spiceworks server is located in the .2 network.

WMI works quite well within .2 but not in .10

I switched all firewalls of temporarily.

I attached a screenshot of one of those pcs, maiking trouble.
I wonder, why I can see the port 135 is operating but it doesn't work.

Thanks for sheding a light on it

Mic
