This dialog controls the net send options.
With the "Net Send" action, short alert messages can be sent via the Windows "net send" facility. These messages are delivered on a best-effort basis. If the recipient can be reached, they will pop up in a message box on the recipient's machine. If the recipient cannot be reached, they will simply be discarded. No buffering takes place. Consequently, the rule engine does not check if the message can be delivered. It will never flag an action to be in error due to a reported delivery problem with "net send".
Net Send Dialog
This is the Windows user name of the intended recipient, a NETBIOS machine name or even an IP address (in the form of 10.1.1.1). You can either use an IPv4, an IPv6 Address or a Hostname that resolves to an IPv4 or IPv6 Address.
This is the message that is sent to the intended target.
