Hi Srinivas,

You can use a Microsoft Tool called Domain Rename Tool

Please read these micosoft articles for more information:

Couple of things....
- You are using Exchange 2010 so off the bat Exchange 2010 does not SUPPORT a domain rename. If you RENAME your internal FQDN it will break Exchange. So do NOT rename your DOMAIN.

See the link below for additional detail on this.

- you can however rename your domain controllers with a different name. However, what you have illustrated above (pdc1 and bdc2) why would you name your DC's like this? You only have 2 and should know what DC is holding the FSMO or PDC roles etc.

- Open cmd (run as administrator)
- Type: netdom computername CurrentComputerName/add:NewComputerName
- Type: netdom computername CurrentComputerName /makeprimary:NewComputerName
- Reboot.
- Type: netdom computername NewComputerName /remove:OldComputerName

Open in new window

Also there are no BDC since NT days. This was PDC and BDC in the NT days because the BDC only had a read-only copy of the NTDS,dit database. In 2000 and up you now have multi-master database replication which means ALL DC's (unless you are using an RODC) are Read/Write DC's. They now call them ADC (additional domain controllers).

Theoretically the DC that is holding the PDC role for the domain is the "authoritative" DC but this role can be easily transfered at any time. So your naming convention IMO is not practical (but do what you like).

To mitigate having to rename the domain you can just create a new Domain Suffix at the top level domain heirachary.
