Hello there,
If you do a repair for your servers from the menu under repair you can make a wbem subscription and send a test event in the second screen. The first screen is to install software, the second is for configuring you software.
Under configure, you can also find the menu option manage communications. With this option you can check if sim can read the remote system and if it can receive events from it. If it can't it will hint you what you can do about it.
Kind regards,
Andrew
