NS records

[kirkgbr at yahoo.com]

Lets say you are running a set of authoritative name servers for
customers.

One particular customer asks you to removed your NS records from his
zone file and replace them with another set of NS records.

what purpose would a customer have for making this request?

Besides breaking the proper zone transfer between your master and
slaves. What else is possibly going to break? 

Go easy on me. 8^)
