Hi EE,

I have a Windows 2003 Root domain and a sub domain where all my users log in.  Recently I added a Windows 2008 domain controller to this subdomain and now am adding a secondary.  When I run dcpromo on the second Windows 2008 server it tells me to run adprep /forestprep.  When I go to the root domain in the forest running Windows 2003 and run adprep32 /forestprep it says it's already done.  What am I missing?

Can you check your schema version

I like adfind http://www.joeware.net/freetools/tools/adfind/index.htm

adfind -sc schver

sounds like you are adding a 2008 R2 box (because of adprep32)

You should be at 44 or 47 more on versions here   http://adisfun.blogspot.com/2012/06/windows-server-2012-rc-schema-version.html

Thanks

What I would recommend is check the actual numeric value for the Schema version using the Active Directory Services Interface. I would perform this operation on both root domain and sub domain to ensure that they both have the same values.

See link below for steps.

ok so you are good on 47, can you check your logs

Dcpromo.log and Dcpromoui.log are located in the % SystemRoot %\debug folder

You can also check event logs.  Verify the health of your domain by using dcdiag and repadmin next if the logs don't help.

Thanks

Ok I downloaded Windows Server Standard 2008 R2 with SP1
I ran adprep32 /forestprep on

forest-wide information has already been updated.
[Status/Consequence]
Adprep did not attempt to rerun this operation.

The Root of the forest is Windows 2003 Enterprise

I also have another 2008 R2 DC that is working so I'm not sure why it wants it run again and why is it not working.

I have confirmed I am running Windows Server 2008 R2 standard on the server I want to promote.  I have confirmed I have the R2 DVD and am running adprep32.  Help!

We have 5 branch offices each with a domain controller at their site and we were 2003 on all domain controllers but recently (month ago) replaced one of the 2003 servers with a Windows 2008 R2 and if I go to ADUC and search computers for all domain controllers this does show so is indeed working as a domain controller.

Now I am trying to promote a new 2008 R2 server to be a domain controller and it wants adprep /forestprep.  I've confirmed I'm at version 47 and ran adprep32 /forestprep from the 2008 R2 media but it says it's arleady done.

We ended up contacting Microsoft and had to reload the OS and then promoted it just fine
