Adding Server 2008 to 2003 Domain

Having trouble adding a windows 2008 server r2 into a win 2003 domain; the domain has 3 domain controllers (2 server 2003, 1 server 2008), all three are at win 2003 forest and win 2003 domain functional level.

I joined the new server to the domain as a member server –all is well. When I run the AD services installation wizard on the new server to “dcpromo” it to a domain controller, I get “to install a domain controller into this AD forest, you must first prepare the forest using “adprep/forestprep”. The utility is available…”

So, I go to each existing domain controller and run adprep/forestprep.  On each one, I get a favorable return “forest wide information has already been updated”.

Then I run adprep/domainprep on each one.  The 2 win2k3 servers tell me the “domain wide information has already been updated”.  On the existing 2008 server, the adprep command just returns a prompt, with no indication of anything running.

All three existing Domain controllers host the Global Catalog server.

On the new 2008 server, I ran the AD installation wizard which completes successfully.  Then,   Dcpromo fails with  the error message above.

What are my next steps?

The above only means you have not not run rodcprep.  It can be ignored.  Can you run repadmin /replsum.  When did you add the current Win2k8 DC?

You are running the wrong adprep you should be running adprep32 please read the article below explaining

Current 2008 DC added 6 months ago.

repadmin /replsum reports largest delta 57-59 minutes and 0 fails.

I obtained and ran (on all 3 existing DC) the 32 bit version of adprep /forestprep = same results, forest wide information has already been updated.

Clear situation: you run a domain using Windows Server 2008  and going to add an additional DC. But this time you plan to have a DC running Windows Server 2008 R2.

But once you start dcpromo on the new DC, you fail with an error message saying you have to run adprep /forestprep prior to add the new box as DC to the domain.

The adprep utility is resided under \support\adprep on the setup disk of Windows Server.

The clue is:
1. Copy adprep folder from setup disk of Windows Server 2008 R2 to the current DC running Windows Server 2008 (previous version).
2. Start it from there, watch for errors and expect successful finish.
3. Re-run dcpromo on the Windows Server 2008 R2 box.

Attention! Do not use adprep from Windows Server 2008 (the version of OS running on the existing DC), take the newest one (from Windows Server 2008 R2).

Run a domain with 3 DC’s: 2003, 2003 and 2008 all domain and forest levels are w 2003.
But once you start dcpromo on the new DC, you fail with an error message saying you have to run adprep /forestprep prior to add the new box as DC to the domain.

Yes, that is exactly the problem.

Taking the DVD for win server 2008 R2 64, under sources, adprep, copy the entire folder to existing DC (w2008) and run adprep /forestprep, it tells me the information has already been updated.

You also said:

Attention! Do not use adprep from Windows Server 2008 (the version of OS running on the existing DC), take the newest one (from Windows Server 2008 R2).

What are the consequences if we did use the older version of adprep, aside from the error message above?

The Schema version of Windows Server 2008 R2 is 47.

Below are some older Schema versions.
13=Win2k
30=2003
31=2003R2
44=2008
So use adprep from Windows Server 2008 R2

again you need to be using adprep32 from the Windows 2008 sever R2 disk

You have to ran adprep/forestprep and adprep/domainprep using DVD of Win server 2008 R2 64
on the existing windows 2008 dc.After the schema is updated you can proceed with dcprom on server 2008 R2.

adprep in Windows 2008 Server R2 is only for 64-bit DCs. adprep32 is used on your current 32-bit DC

I did as suggested, same results.  I even went to M$ website, did the “request a hotfix” thing, got WindowsServer2003-KB919151-x86-ENU.exe, and used this version of adprep. Every occurrence is giving the same result: “information is already updated”.

So, for fun, I ran dsquery * cn=schema,cn=configuration,dc=domainname,dc=local -scope base -attr objectVersion  (with my domain name…)

On all 3 existing DC’s the command returns objectVersion 44, which, according to MS is 44 -> Windows Server 2008 RTM.

Windows 2008 Server R2 is 47

Did you go to the Windows 2008 Server R2 DVD find adprep32 run the commands for this and only this. Adprep is not correct if you are currently running 32-bit DC.

Ran D:\2008DVD\Support\Adprep\adprep32 /forestprep on the server holding the Schema Master role.

Ran D:\2008DVD\Support\Adprep\adprep32 /domainprep /gpprep on the server holding the domain master role.

Also check forest and domain functional level is raised to Windows Server 2003.

The server is from Dell.  On the disc supplied, there is no aprep32 folder.

I connected to the ms licensing site and and downloading a full copy of win server 2008 R2, as I've read elsewhere that adprep32 is now included in the 64 bit disc.  Hope so.

You need adprep32 which is on the Windows 2008 Server R2 DVD if you read the link I posted this will give you exact instructions. If you don't have which is you have a Windows 2008 Server R2 DVD you will have this file you can download another copy of Windows 2008 Server R2 it must be R2

Commented:
Ok, I got adprep32.exe from the R2 DVD, ran it on each of the existing domain controllers.  In all 3 cases, the command merely returned a command prompt - no indication of success or failure.

Then, back to the R2 2008 server, install the AD role (works); run dcpromo and it fails with the same error as above (must run adprep/forestprep).

DSQUERY says I'm still at version 44.

The command didn't run properly then you should be running on schema master from the DVD. Give me a screenshot

Commented:
Oh, for crying out loud.  I forgot to copy all the supporting files along with adprep32.exe.  It works.  Now, I'm waiting for the replication to complete.  I'll keep this thread open for a day or two more and try the dcpromo on Sunday.

It's working.  Many thanks, everyone!
