RE: [ActiveDir] Multiple forests with a common DNS parent zone

Title: Multiple forests with a common DNS parent zone

Based on the configuration explained below, there should be no problem.   Aric   From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Monday, October 03, 2005 2:30 AM To: ActiveDir@mail.activedir.org Subject: [ActiveDir] Multiple forests with a common DNS parent zone   I have encountered a situation where 4 forests exist today, all of which have a common DNS parent zone - let's call it xxx.com. Forest 1 has root domain named xxx.com with multiple child domains Forest 2 has root domain named ap.xxx.com with multiple child domains Forest 3 has root domain named am.xxx.com with multiple child domains Forest 4 has root domain named jp.xxx.com with no children DNS resolution between the 4 forests works fine. Xxx.com is hosted on UNIX BIND servers with all child zones delegated to Windows DNS servers. All child zone DNS servers forward to the servers hosting xxx.com. Existing forests are w2k native and no trusts exist between these forests.   There is a proposal to build a new, fifth forest and to migrate all objects from the 4 forests above into this new forest. Forest 5 will have root domain named global.xxx.com and 4 children - representing the 4 forests above. Does anyone have any concerns over the re-use of the same DNS name - xxx.com? I feel uncomfortable with this proposal but don't have any technical reasons to block it. Any comments?
