DEP related backup failure on 3 similar databases
"To help protect your computer, Windows has closed this program."
Name: SQL Backup Service Application
Publisher: Red Gate Software Ltd.
A quick search of the forums yielded little help. DEP issues existed once, but "were resolved" in 2007.
I'm not sure which log(s) are most useful, but I can post them if requested.(since the service stopped, the GUI doesn't register this backup)
