Guest Juan García Posted July 1, 2008 Posted July 1, 2008 I would like to format a server that is DC (with GC), reinstall the SO and I need set the same name to the new reinstalled server. What should I do?? Thanks.-
Guest Zaur Bahramov Posted July 1, 2008 Posted July 1, 2008 Re: Reinstall DC Hi! Well, you will need another server which will retain AD and FSMO roles while you reinstall this server. Pls, see here for transferring FSMO roles: http://www.petri.co.il/transferring_fsmo_roles.htm The recommended process is as follows Install Windows 2003 on the new machine Assign the new computer a new name, IP address and subnet mask on the existing network Make sure that the preferred DNS server on new machine points to the existing DNS Server on the Domain (normally the existing domain controller) Join the new machine to the existing domain as a member server From the command line promote the new machine to a domain controller with the DCPROMO command from the command line Select �Additional Domain Controller in an existing Domain� Once Active Directory is installed then install DNS. You can do this through Add/Remove Programs->Windows Components->Networking Services->DNS. If you are using Active Directory Integrated DNS then DNS will br replicated from the other DC/DNS. Next make the new machine a global catalog server, go to Administrative Tools, Active Directory Sites and Services, Expand, Sites, Default first site and Servers. Right click on the new server and select properties and tick the �Global Catalog� checkbox. (Global catalog is essential for logon as it needs to be queried to establish Universal Group Membership) If necessary install DHCP on the new DC. You can do this through Add/Remove Programs->Windows Components->Networking Services->DHCP. You will then need to remove any existiing DHCP prior to authorising the new DHCP Server. When setting up the new DHCP server don�t forget to set the default gateway (router) and DNS Servers. Talking of which all the clients (and the domain controllers themselves) need to have their Preferred DNS server set the new domain controller. Transfer all the FSMO roles to the new DC: See http://www.petri.co.il/transferring_fsmo_roles.htm You can copy data from the old to the new machine (use robocopy or xcopy to retain NTFS permissions), you will need to reshare any shares. Both Domain Controllers by this point will have Active Directory, Global Catalog, DNS and the domain could function for a while at least should any one of them fail. You can/should keep the old DC on line - it will provide redundancy should the other server fail - better to to this than keep if off-line as you suggest. If you really want rid of the old DC then:- Check that you have:- Moved the FSMO roles Made the other DC a global catalog: Installed DHCP on the new DC, set up the scope and authorise it. (If using DHCP) Make sure that all clients use the new DC as their Preferred DNS server (either by static or DHCP options) Power down to old DC and make sure that all is well, once satisfied power on the old DC again, then run DCPROMO for remove it's domain controller status. This is essential to avoid replication errors If you want to remove the machine from the domain then you can do so one it's DC role has been removed "Juan Garc?a" <XXnl144039YY@ZZgmail.com> ha scritto nel messaggio news:OlMmdQ12IHA.4448@TK2MSFTNGP05.phx.gbl... >I would like to format a server that is DC (with GC), reinstall the SO and >I need set the same name to the new reinstalled server.
