Adprep success, DCPROMO fails

[colin8651]

I currently have a 3 Windows 2000 Servers (SP4 on all current DC's) and I just purchased a new server which I installed 2003 x64 R2 on. I am in the process of running DCpromo and get the adprep error that you get when your current domain hasn't been prepped with the adprep tool.

After fixing a role problem that was preventing adprep from running I ran both "adprep /forrestprep - adprep /domainprep" on the global catalog server and both reported success. After I let replication occur I tried to make the new server a DC and still get the same message "the version of the Active Directory schema of the source forest is not compatible with the version of active directory on this computer."

Here are the logs from adprep that I ran a second time on the Global Catalog:

Forest-wide information has already been updated.

[status/Consequence]

Adprep did not atempt to rerun the operation

Domainwide information has already been updated.

[status/Consequence]

Adprep did not attempt to rerun the operation

After checking my dcdiag I found that everything passed including my FsmoCheck.

I don't know what else to check; is their a way to manually check each server and ensure that they are all prepped?

PS, I did find an error in dcdiag when I used the /q tag

I would suggest first installing Windows 2003 x64 on the server, sans R2, and upgrade the domain functional level to 2003 mixed mode after moving the FSMO roles to the 2003 server. After that, run adprep /forestprep and adprep /domainprep from the R2\adprep folder and see if that works for you.

Thanks for the help; But I have a stupid question.

I only have the 2003 R2 and 2003x64 R2 from Dell licensing; is their a way I can install without the R2 with the media I currently have?

[colin8651]

Wow you were correct it was the R2. What is it about the R2 that does that?

Thank you for your help.

Installation of R2 requires two things - one, a Windows Server 2003 server as a DC (has to ALREADY be a DC, not one you're installing with R2 already installed), and second, at least a mixed-mode domain. R2 is unable to upgrade the schema from anything but a Server 2003 DC (obviously without R2 installed, because you can't install R2 without first updating the schema). You cannot install R2 into a domain that doesn't already have a Windows Server 2003 DC, because you need that machine to upgrade the schema to allow R2 installation - it's roundabout, but makes sense if you break it down .

to promote a 2003 R2 server to a domain controller you will need to run the R2 adprep

adprep in the i386 directory of your 2003 R2 cd will not work, it needs to be the adprep from disc 2

in the D:\CMPNENTS\R2\ADPREP\ directory

this one caught me out last week

Now I had a problem running adprep because it was from x64 R2 CD2 and I was trying to run it on Win2000 Server.

So what I did was, I got win32 version of R2 CD2 and run adprep on my Win 2000 DC, both /forestprep and /domainprep, and then DCpromo was done with no problem on my new Win2003 R2 x64 server...
