ARD Database Package

Hi everyone! InstaDMG is working awesome. Thank you again! I hope this is the right spot to post this. I am interested in making a package or script that reports to remote desktop the ip address, etc the first time a newly deployed machine logs in. It doesn't necessarily have to access the ARD database. It just needs to make a list of machines somewhere so I can compare it to my ARD lists to keep them updated. Let me know if this makes sense or if you have any better ideas. Thanks for any input!! Steve
