  • PTR record being wiped out

    We've got one server whose pointer record is being wiped out every time I put it in. I've tried ipconfig /registerdns and I've tried inserting a static record. Neither will stick around longer than 1 hour. Our aging settings are set as follows:

    no-refresh interval: 8 hours
    refresh interval: 8 hours
    scavenging interval: 7 days

    I know these settings aren't optimal, but they shouldn't allow a record to be scavenged after just 1 hour. Also, it's my understanding that static records are never to be deleted except manually. Any ideas on this would be appreciated.
