Legacy DNS Delegations - Can I remove?

Hello Technicians,

I have two DCs running Server 2008 R2.  Within our DNS > Forward Lookup Zones > domain.com folder we have two delegations (defaultwg & default_wg) that list our previous name servers.  Because of this information I don't believe there is any reason to keep them, but I wanted to through the question out there because our domain's Pre-2000 Name is defaultwg.

Feel free to comment back with any questions.

Do you have forward lookup zones called defaultwg.domain.com and default_wg.domain.com?  If not the delegations aren't doing anything (and can certainly be deleted).

However, I'm confused as to why you would have them.  Just because a domain's NetBIOS name is whatever, doesn't mean that there should be a matching zone in DNS.  They are two different name resolution mechanisms (NetBIOS vs. DNS), and one doesn't depend on the other.

FooTech,

To be honest with you this setup was before my time, so I can't comment on why those delegations were there.  However, there are not forward lookup zones by those names, so I am going to be deleting them.

Thank for the help!
