Rebuilding an RODC

I have an RODC in a remote site. It is currently running Server 2008 32-bit. Company policy is for all servers to be 64-bit. Is it possible to demote the RODC, remove it from the domain, install Windows 2008 64-bit and promote it to an RODC using the same hostname, or does it have to have a different hostname?

On a side note, we are in the process of migrating our workstations to Windows 7 from Vista. We have 2008 R2 licenses. Is it worth installing 2008 R2 on the RODC or stick with 2008?

As long as it is removed from the domain correctly then there is no reason why you cannot use the same hostname.

If you have 2008 R2 licenses and you are rebuilding then use them

Commented:
R2 is prefered to be installed then one without. It has more updates & bug fixes then 2008. It also provides you with a better OS for hyper-V if you use that.

demote the rodc & then move it to a workgroup. If all was scucessful with no error then reinstall with new OS & same name.
If you run into any errors & can not fix them then a new name will be a better way to go.

Yes this should not be a problem. Make sure that you demote the machine from its RODC role first, then remove it from the domain. You can then add the 64bit machine with the same name and promote that to be a RODC.

you can use the same name.
 
however, make sure the OLD server is not available anymore after demotion and using the same name. After demotion do not forget to delete the server object of the RODC manually!

Thanks for the comments. One final question. If I use R2 for the branch RODC, will I need an R2 writable DC in the main site before the RODC is deployed?

Commented:
no, at least a w2k8 rwdc
