Ports for Windows monitors

I'm using the evaluation version 7.14.1. I will be using ServersCheck in an environment with Windows Firewall on several hosts that will need to be monitored. If I turn off the firewall on the host I want to monitor, WINDOWSHEALTH monitor works. When I turn the firewall back on, SC returns the error "Unknown". I have opened the ports 135 TCP and UDP and ensured that 445 and 139 TCP are also open on the target host. Are there more ports that must be open? If not, what could be the problem?

See http://wiki.serverscheck.com/index.php/Firewall and the remark at the end:



Depending on your remote host's configuration, RPC dynamic port allocation may be active. This will instruct the RPC program to use a particular random port above 1024 and not just the ones defined above. For more information on how to configure RPC in such conditions, please refer to following knowledge base article from Microsoft: http://support.microsoft.com/kb/154596/

Thanks for your quick response. I did read the KB article, but it appears that it applies to servers, while I am running XP Pro on my local and remote hosts. I will try this method, however, and see if that solves the problem.
