A couple of queries:

- Can one copy users/groups/permissions from one windows server to another?
- Can one export lists of broadcast points and their settings from Windows Media Server to an installation of Windows Media Server on a different machine? If Windows doesn't do this would it be possible to write a tool to do it? Does anyone have experience administering WMS?

TIA!

I personally don't have much experience in this, but this topic might be able to help you out Arta.
