Cross-posting is generally frowned upon when your question is open on one site, since the community there sometimes will migrate it to another site. In this case cross-posting just creates duplicates that someone has to come and deal with. If the question is closed as off-topic, though, it can be re-posted on a more appropriate site.
Unfortunately, Server Fault doesn't appear to be the appropriate site, as it doesn't appear to have anything to do with professional system or network administration.
I've migrated your question to Super User, where you should be able to get an answer.
