 Posted: Tue May 16, 2006 5:05 pm Post subject: Additional DC 2003 vs 2003 R2 |
 |
|
I am getting the error that the active directory schema is not compatible.
I think I know why but here is my situtation.
Server A: w2k (Original AD/DC) DNS, DHCP
Server B: w2k3 Enterprise added no problems, DNS,DHCP
Server C: w2k3R2 Standard
I was able to add server B, run adprep /forestprep and /domainprep on Server A
Then added Server B no problems.
I am now trying to add Server C but I get the error that the schema is not
compatible.
Is it because I need to run forestprep and domainprep for w2k3R2?
If so which DC? Both Server A and B?
My next task will be to remove Server A from the equation how do I go about
doing that?
I think I need to transfer the FSMO from Server A to Server B.
Any hints would be helpful.
Thanks |

You have to run "adprep /forestprep" (adprep from the w2k3 R2 disk 2) only
on the schema master. For more information you can read kb article:
http://support.microsoft.com/kb/917385/en-us.

When a domain controller is demoted, if it is not the last domain controller
in the domain, it performs a final replication and then transfers the roles
to another domain controller. If the domain controller is a global catalog,
that role is not transferred to another domain controller. Read the article:
http://support.microsoft.com/default.aspx?scid=kb;en-us;238369
To set another DC as GC (BEFORE DEMOTING) read the following article:

Thanks for the good info.
I have a follow up question.
When I run adprep /forestprep on the server A which is my master currently.
Does it need to be off the network or can I run forestprep while it is still
connected to
the network?
It says nothing about taking it off the network but last time I ran this
(adprep /forestprep) I had it off the network.
Thanks

I read this article:
http://technet2.microsoft.com/WindowsServer/en/Library/ed42abd5-24c7-4b5a-8165-dbd96727ec841033.mspx?mfr=true
Since it's not differently specified, you can run adprep while the server is
still connected to the network.
