My active directory server has been "broken" for some time but is still functional. There are many issues with my AD server one of them being that replication of settings and user account do not migrate to other member servers nicely.

I recently have been given the OK to get our Windows 2000 AD and Exchange 2000 servers "upgraded" to Windows 2003 and Exchange 2003. I'm really not that concerned with my AD info but my Exchange data is of the utmost importance. How can I install a new Windows 2003 AD server and make sure that I will be able to access my Exchange user data when done.

If you are concerned with your exchange data, I also suggest that you run Exmerge to extract all your mailboxes to PST files (just for incase)  Remember that only backing up the mdb files will  not ensure a safe return from a failed migration.

A standard "upgrade" is not an option, this was confirmed by me just trying to promote another member server to a BDC. The DC promo worked but all of the functionality that was "broken" in my AD or PDC was also broken in the BDC.

I need a "path" that will allow me to create install a new Windows 2003 AD instance and somehow preserve the links that it has to my Exchange 2000 install. If I just install a new Windows 2003 AD and a new Exchange 2003 install and re-create all of my user accounts and such... is there a utility to pluck out the user data in the existing Exchange store and move it into the new Exchange instance?

That is not going to happen.  The Exchange is linked to the domain, so if you lose the domain, you lose the Exchange.  

All you can do at this point is to use CSVDE to extract your users and groups for import to the new domain and then to extract your mail using Exmerge.  You then have all you need to recreate an environment without retaining the old domain, but retaining all the mail in your exchange.

Hello itcoza:

That sounds like it may be just what I'm looking for, I will be able to use the same domain name and such - correct?

I understand that the CSVDE tool will gather user and OU's information but do you know if by using the CSVDE (or another) tool, will I be able to retrieve group policy objects and such?

Regards,

CBS

Hi,  Sorry that I have not come back to you on the final question...

You can use the same domain name, but note that you will not be able to just continue with your workstations as is.  They will have to be removed from the current domain to a workgroup and then be joined to the "New" domain again once it has been created.
CSVDE will not export the GPO data.
