Adding Windows 2003 Server to existing Windows NT 4 Domain....

I am going to be adding a Windows 2003 Server to an existing Windows NT 4 domain, and don't want to have to unjoin and rejoin anything nor have to redo all of the user profiles.  How should one go about this?  How can Active Directory be added?  Thanks.

You have to promote it to PDC before upgrading it.

It's been a long time :-) you are all right... you have to upgrade to PDC and keep the old "pdc" which is now "BDC" away so that you roll-back in case anything goes wrong.. that's exactly  how I did it in 2001! can't believe it's 5 years back already!

Hi everyone,

Thanks for your input so far.  I found this article that is labeled "Supported upgrade paths for Windows 2003 Server".  

http://support.microsoft.com/kb/810613/en-us

It just states the following for Windows NT 4.0:

• Microsoft Windows NT Server 4.0
You must upgrade Windows NT Server 4.0 programs to Service Pack 5 (SP5) or later before you upgrade to Windows Server 2003.

So, does that mean you can just upgrade your PDC to Windows 2003?  How does Active Directory get the user profiles from the SAM database into the Active Directory database?  Thanks for you help!

it imports... you don't need to to do anything special except follow the installation instructions

Ok, but actually, I just want to add a Windows 2003 Server to the NT 4 domain, make it the PDC, then somehow import the SAM database into Active Directory.  Can this be done?  Thanks!

No.

All the information above explains this to you.

You either need a new domain and use ADMT to migrate users and computers or you upgrade the PDC then add the new hardware with 2003 to the domain as a DC, move the roles, make it a GC, install DNS and copy over any data before you demote the old server.
