Question

How to rename primary domain controller server name ?

Asked by: netcool

I have done a  silly mistake during my uprade of WinNT4 server to Windows 2000 Server OS.
After the upgrade completed, the active directory wizard prompt for domain server info and  i provide the wrong information in the setup.

Now the full computer name of the server become Oprs0001.Oprs0001.bpc.com.my and domain name become oprs0001.bpc.com.my.

The actual server name is = oprs0001
domain name is is = bpc.com.my

I wonder if there is a way or method to rectify the mistake that i make in the active directory setup. Because, i am not able to upgrade my BDC to windows 2000 OS due to the mistake above because it con not find the domain name oprs0001.bpc.com.my.

Thank you.

Hi Netcool,

Win 2000 will not allow you to change a DC host name as long as it is a DC.

Run DCPROMO to remove it from the DC role, remove it from the domain, change the host name, rejoin the domain(correct one) and then run DCPROMO again to promote the system back to DC role.  This forces a DNS update also.

After taking the server out of the Domain, be sure to reboot it before adding it back into the domain to clear out the DNS listing.  After you have added it back, etc., with the new name, check your DNS to be sure the old name is gone and the new is now listed as a domain member.

Regards
Stevengreen

Will this effect my user account and file sharing, becasue there are a few applications rely on this PDC for login to the system to run program. What is the safe way to do this because i was trying to promote a server to DBC so, other applciation server will not have impact but not not sucessfull due to error message con not find suitable domain.

I'm not quite sure I understood the question totally.

This will affect users logging into your domain if it's the only domain controller on the network.

Is this your only domain controller? If it is, any applications requiring domain login to function will not fucntion until the domain is backup and running.

you may want to promot another machine temporarily to DC until you have the other machine fully functional and then demote the other machine?

DO you have an image of the old server before you did the upgrade?

 

by: mikeleebrlaPosted on 2004-07-07 at 08:06:56ID: 11492565

if you have applications that point to the old server name,, of course they will not work anymore since the old server name doesn't exist,,, so you will have to "point" your clients to the new server name now.  it will NOT effect your users if you have multiple DCs and they are set up correctly.  just to clarify some terminology used here,, PDC and BDC are NT4 terms... in a windows 2000 environment there are no such things as a BDC or PDC,, servers are either a DC or not.  Make sure that the server that you are removing doesn't have any of the 5 FSMO roles and also make sure that you have another global catalog server somewhere on your network.  Look at this link regarding FSMO roles:

There are two ways around this: Revert back to an NT4 domain, then upgrade again, using the correct domain name; make sure you have working backups of all machines involved:

I was thinking is it possible to alter the name in the registry and reboot the server.
Another option is the windows 2000 support tool (Active Directory Adminsitration tool) able to make the changes to the server.

Below is the info extracted wit hteh tools mentioned above.

Sorry, but If it would be that easy to rename a domain, don't you think that Microsoft wouldn't have bothered suggesting a lengthy procedure involving an NT4 BDC, then finally offering an officially supported possibility in Server 2003?
