you have to open 135/tcp to do the remote admin connection and then anything >=1024/tcp for the ephemeral port that WMI uses. that is the default anyway even though a static port can be configured, that may be too much to ask of the windows admins depending on your environment.
Version is 9.01, and the 135/TCP is already open. Just like Marcus said, that's too much to ask here, so what I'm looking is for a document that explicitly says the firewall ports they should open; document is enough support for them.
Unfortunately, I've searched into the manuals without success. If anyone knows about any document, even if not from HP, please tell me where to find it, thanks.
would have pasted one, but the one I generally reference seems to have been removed from Microsoft's MSDN site. However, WMI uses 135/tcp to do the initial connection. However, WMI relies on DCOM services as well thus why you have to also open 1024-65535/tcp as well.
Its like passive FTP in that way. Just opening port 21 is not good enough because that's the just control port. after the 21/tcp connection is established, another port is chosen somewhere between 1024 and 65535 (or whatever range the server is configured with) to use as the data port.
WMI needs that DCOM port to do the data communication or it will fail to function properly.
