Migration to Windows 2000 DNS

The first step in migrating non-Microsoft DNS servers to the Windows 2000 implementation of DNS is to introduce Windows 2000 DNS servers as secondary servers for the overlapping zones. One of the key points here is to configure a zone transfer from a master to a secondary Windows 2000 DNS server and make sure that the zone transfer process does not generate any errors. Errors can occur if during the zone transfer the Windows 2000 DNS server is not able to recognize records sent by the non-Microsoft DNS server. These records should either be repaired or removed from the zone in order for the zone transfer to complete successfully.

Once the Windows 2000 DNS servers have stabilized in the new role, their
