I hear you. I do know what the switch achieves in terms of functionality, I understand the litterature, have done this, have explained the same to clients, however I am faces with the Question of Why this is a non reversible switch?

This is understood, however, what are the implications of manually re-writing the nTMixedDomain value back to 1? Also, what actions does a DC take once the value change is efected that makes the cange non-reversible? -----Original Message----- From: Jorge de Almeida Pinto [mailto:[EMAIL PROTECTED] Sent: 20 April 2005 08:17 PM To: 'Nicolas Blank '; '[EMAIL PROTECTED] '; '[email protected] ' Subject: RE: [ActiveDir] Native Mode Switch When you convert the domain to native mode the attribute nTMixedDomain on the domain NC head of the replica where the change is made is changed from 1 to 0. This change replicates out to all other replicas. There is no way you can change this attribute back without doing a disaster recovery for the domain. The main thing here is that you don't have legacy DCs in the domain anymore!!! I can think of the following solutions to test the change of the mode switch: * Create a copy of the particular machine with the SNA application and test that in a test environment * Create a full backup of the particular DC with the SNA app, disable OUTBOUND replication for that DC (REPADMIN) and change the mode switch. If something goes wrong restore the DC and enable replication again (the latter is needed as the restored DC will receive the disabled state from the other DCs.

Appologies. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Nicolas Blank Sent: 20 April 2005 07:21 PM To: [email protected] Subject: RE: [ActiveDir] GC's Eric,Joe,Al,Carlos,Guido Question for you guys and the wider audience. What happens EXACTLY in Win2k on a DC(s) when the native mode switch is pushed, and what are the ramifications of changing the attribute back to reflect mixed mode one this has happened? I have a customer with a nervous disposition that doesn't believe me when I say there ain't no way back that's supported without doing a AD DR. Background is a business critical SNA application that HAS to live on a DC. MS is cool about switching to native, but customer is REALLY nervous. Any insight will be appreciated.
