Internal DNS conflict with public DNS

[zaccaz]

hi there,

due to historic issue, internal W2K3 AD network was named as "mydomain.com" with 192.168.0.x segment, of coz internal DNS server was setup with records of 192.168.0.x entries

unfortunately there's public domain “mydomain.com” resolved as 999.888.777.666 (this is fake ipaddr for explanation purpose) in used by other company, in some strange cases client will resolve server1.mydomain.com as 999.888.777.666, server2.mydomain.com as 999.888.777.666 (i.e. whatever.mydomain.com will be resolved as 999.888.777.666)

wondering is there any easier tricks to overcome this?

many thx!

What you need is 'split-brain' DNS
