To open a web page on the remote machine you can add before your message ~~

If run using the /client switch, just add before the message ~~

ie.: ~~http://www.google.com

If you use it from command line the applicable call would be

rmsg.exe 192.168.1.2 “~~http:\\www.google.com”

The same interface can also be used to call a webpage w/out http:\\ in front.

rmsg.exe 192.168.1.2 “~~www.google.com” is also a valid call.

You can also use the same interface to call media files to play.

rsmg.exe 192.168.1.2 “~~C:\mp3\mymusic.mp3″

By default rmsg will attempt to call the default program associated with the extension of the file. If no default program is given it will attempt to run cmd.exe /c “start file” so as to prompt for the user to select an applicable program.
