Exchange Server 5.5 on Windows 2000 Server 1

[LPhan]

Hi ! All

I have Exchange Server 5.5 on Windows NT PDC and now I install Windows 2000 Server with SP4 on a new computer. I migrated all users account from windows NT to windows 2000 server active directory and then I install Exchange Server 5.5 on computer W2K server to join exsiting site on windows NT4 PDC. All the installation is succesfully. When I run Exchange Server Administrator on Windows 2000 Server, it show 2 site , 1 on windows NT domain, 1 on windows 2000 server because those 2 computer has different computer name but same domain name.
Is it possible for client users send mail if windows NT domain shut down or I need to set up on outlook on client stations.
I really need help about this. Are there anyways to rename the site in windows 2000 server active directory.

Please Please help.

You need to move all of the mailboxes to the 2000 server, change the bridgehead to the new one and migrate any other settings from the old server. Then you can remove the old server from the organisation and shut it down.
