Speedy Posted February 17, 2005 Report Share Posted February 17, 2005 Hi all. I need to upgrade our primary domain controller running at NT4 Server to 2000 Server. But I need to keep all settings, mainly our domain. Will domain and trust relations remain "untouched" after upgrade? I tried to find some related whitepapers or documentation, but there's nothing about trust relations, so I'm not sure.Btw, we have only primary DC and no secondary (or backup) DC. What do you suggest is the best way how to upgrade it?Thx. Speedy Quote Link to comment Share on other sites More sharing options...
miket Posted March 1, 2005 Report Share Posted March 1, 2005 Hi I have the same task, but have to blow everything away as the RAID arrays need re-configuring. I think we have to create a temporary BDC and then promote it to tbe the PDC. Then upgrade it to 2000/AD. Then blow away the original server and install 2000, joining the new AD domain. Then make this server the master and remove the temporary one.Can someone confirm this procedure ?Cheers Quote Link to comment Share on other sites More sharing options...
spikeychris Posted March 1, 2005 Report Share Posted March 1, 2005 I would go along with miket on this, to install a new NT4 BDC, promote it to PDC and upgrade it to Windows Server 2003 DC. So, you just need to setup a new BDC and refer it to the original NT 4 DC. This is how you would do it on a migration to 2K3.Microsoft has relesed this info regarding How To Upgrade a Windows NT 4.0-Based PDC to a Windows Server 2003-Based Domain Controller here Quote Link to comment Share on other sites More sharing options...
homecomputeraid Posted March 2, 2005 Report Share Posted March 2, 2005 Hi Speedy,Any reason you're going to 2000 Server instead of 2003?Trust relationships are quite different from NT in 2000 and 2003. There's an implicit two way trust between domains in the same forest, where in NT each trust had to be established manually.I recommend putting in an NT BDC also before the upgrade. It can be a regular PC with NT Server installed. Quote Link to comment Share on other sites More sharing options...
miket Posted March 2, 2005 Report Share Posted March 2, 2005 My customer requires 2000 for a specific application. There are no trusts with any other domain. Quote Link to comment Share on other sites More sharing options...
nellie2 Posted March 2, 2005 Report Share Posted March 2, 2005 Speedy replied but he hit the report button instead of the reply button, that happens a lot, perhaps we should shift the buttons around! :blink: Anyway, this is what he said today at 12:26Yes, this should be the best way and probably the only one. I've just created a BDC on NT4 and made complete backup of domain. But the main question still remains: will the trusts remain? I'm not sure, that after promoting BDC, upgrading original PDC a then rejoining domain it will be the same domain. I think, that maybe domain's SID should change after this process.I've read this material and lot of others, but there's nothing clear about trusts :(.

homecomputeraid Posted March 2, 2005 Report Share Posted March 2, 2005 I'm not sure why you're worried about trust relationships if you have no other domains. Are you migrating to a Windows 2000 Active Directory infrastructure from a single Windows NT Domain? Make sure you tell the server you're going to be in mixed mode during the installation, and you should be fine.When you say trusts, do you mean rights?
