I have used Scavenging in several environments before. I know about the common gotchas (Needs to be set on server AND zone, takes longer than you think) but I am still coming up short. Worse part, there are three of us scratching our heads over this. The zones are all AD-Integrated. The times are all set for 1 hour. We have isolated one DC in our lab (two actually, one parent.net one child.parent.net) and grabbed all the FSMO roles just in case the problem is somehow related to the AD part. DNS is logging Event 2502 every hour. Each zone is way past the "safety valve" time. I cannot get a 2501 to show on any zone. This has been tried on the three zones in the child domain and two zones in the parent. No records are being scavenged. Where should I be looking?
