lookout 5 cannot find computer - win xp sp2 problem?

[frisk]

I'm receiving this message when I try to connect to a machine in Lookout 5 object browser:

Lookout cannot find any resources on the specified computer. This computer may have become disconnected from the network.

The computer is not disconnected from the network, network connection is fine, ping and explorer browsing work fine. Object explorer lists the computer, but when I try to open it I receive the mentioned message.

The only thing that I noticed odd is that problematic machine runs xp sp2, and other does not (it runs sp1). When I try to connect with other machine that also has sp1, all works fine.

Anybody has a clue? Is this sp2 problem and is there a work around?

Thanks,

Darko

Looks like sp2 for win xp brings plethora of opportunities for driving me
away from less important work like design and programming to by far more
important tasks like installing drivers and connecting to computers. My
problem from previous post is solved by disabling xp firewall.

I would be most appreciative if someone from NI would list the apps and
ports for Lookout 5 which should be removed from sp2 firewall's attention.

Thank you,

Darko

The following KB article, and the links therein, discuss the SP2 and firewall issues for Lookout (and other NI products).  One of the links lists the ports used, etc., as well.

If the above link doesn't work, search for KB article # 37H7JBQA.
