Microsoft Server 2000 Docs - The configuration of PTR resource records and reverse lookup zones for identifying hosts by reverse query is strictly an optional part of the DNS standard implementation. You are not required to use reverse lookup zones, although for some networked applications, they are used to perform security checks.

You don't specifically need pointers...as far as I can remember it is just good practice. I do find it useful from an admin persepctive at times, i.e. resolving an IP back to an IP in a troubleshooting scenario (at times). You aren't going to lose anything by creating them. Rob -----Original Message----- From: Jan Wilson [mailto:[EMAIL PROTECTED] Sent: 30 May 2004 02:22 To: [EMAIL PROTECTED] Subject: [ActiveDir] PTR records - why? We have a Windows 2000 forest with multiple child domains. No web servers. No remote hosted mail servers. No external access. (That I know about at least!) Our DNS is integrated to active directory. Fellow administrators are adamant we should create reverse lookup zones for all our subnets. This would assist name resolution for our NT4 workstations they claim. Stuff and nonsense I claim. Is there any reason to use PTR records on an AD domain? Thanks!
