2003 AD servers and 2008 AD

Hi

I have a 2003 R2 domain with two AD servers. One of the servers has suffered a hardware failure and can't be recovered.

I have a 2008 R2 server and I was wondering if I made this a AD server would I be okay to run a 2003 R2 AD alongside a 2008 R2 one until I have can at a later date get a second 2008 licence and can create another 2008 server and decommission the 2003 one?

I understand I would first need to prep the 2003 domain for 2008.

Thanks

Yes, as long as you prep the domain for a 2008 DC

Where should I run ADPREP?

ADPREP /forestprep must be run on the Schema Master of a forest and under the credentials of someone in the Schema Admins and Enterprise Admins groups.

ADPREP /domainprep must be run on the Infrastructure Master of a domain and under the credentials of someone in the Domain Admins group.

Also, if the crashed 2003 DC had any roles, you will need to seize them and use ADSI edit to remove the metadata from AD for the crashed DC.

Yes what you want to do is fine, a few points

You will need to prep your forest/domain.  You mentioned 2008 R2.  If you current DCs are 32 bit use adprep32

With the DC that failed I'm assuming you were not able to demote it gracefully.  You will have to clean that DC out of AD (known as metadata cleanup   http://www.petri.co.il/delete_failed_dcs_from_ad.htm)

Did that dead DC hold any FSMO roles?

Thanks

Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

Thanks for the replies

Should I remove references from the domain of the dead AD server via metadata clean up first before prep it for 2008 and adding the new AD server?

I would seize the roles before removing it from ADSI edit. Get it running good, then worry about the cleanup

I'd remove it first, only takes a few minutes.

Make sure all of the roles are running on your remaining DC's before doing the cleanup and prep.
