SYMPTOMS
If you have a Domain Name System (DNS) server hosting secondary zones for parent and child domains, deleting the child domain removes the delegation for the child domain from the the parent or  domain.

For example, if your DNS server hosts the following secondary zones
 * domain.net (root domain)
 * child.domain.net (child domain)

and you delete child.domain.net from the secondary server, the NS delegation for child.domain.net is deleted from the domain.net zone.



CAUSE
This behavior occurs because the copy of the zone is running in memory.

NOTE: This is not written back to the zone file.



RESOLUTION
To resolve this problem, use the following syntax at a command line: net stop dns

net start dns Using this syntax stops and starts the DNS service, which reloads the parent or  zone, and the NS delegation record reappears.



STATUS
Microsoft has confirmed that this is a problem in Windows NT 4.0.
