Sandbox error

Hi,
I’ve been creating a fla that reads an XML file, that tells which swf to import. Finally got that all working and put it on the local network at work, only to get a sanbox error. It seems for some people the main fla will work for people, but the xml isn’t loading the content. I’ve read some about having to include a domain in the xml, giving permission to domains named. The problem I’m having trouble with is what do I do for a local network? And were going to be sending it to other people who will be running it on their local computers or their office networks. Any help would be greatly appreciated, I have little experience in this area.

Please let me know if there is more info that would help.
