ADPREP issues - not working?

[jebenson]

Hello all,

I am running a Win 2000 domain with 2 servers. I am adding a new server with Win Server 2003 R2. While trying to set up AD on the new server I got the message telling me to run ADPREP on the schema master and the infrastructure master. I followed the instructions and ran ADPREP with the /forestprep and /domainprep switches. No errors were thrown in the command prompt. I have given it time to replicate to the other server (one server holds both the schema and infrastructure master roles), but I am still getting the "incompatible AD schema of the source forest" error, and AD will not install on the W2K3 machine. I tried running ADPREP again, but it said that nothing to be upgraded and did not run.

I checked the event logs on the schema/infrastructure master, and there were no errors. I then checked the error log on the other domain controller, and there were some error messages:

Class identifier 655562 (class name msWMI-MergeablePolicyTemplate) has an invalid superclass 655560. Inheritance ignored.

Class identifier 655570 (class name msWMI-StringSetParam) has an invalid superclass 655563. Inheritance ignored.

Class identifier 655566 (class name msWMI-IntSetParam) has an invalid superclass 655563. Inheritance ignored.

Class identifier 655567 (class name msWMI-UintRangeParam) has an invalid superclass 655563. Inheritance ignored.





These errors were followed by a few information messages:


An index on the attribute 591542 (msDS-AdditionalSamAccountName) was successfully created.

An index on the attribute 591266 (msDS-Cached-Membership-Time-Stamp) was successfully created.

An index on the attribute 591446 (msDS-Entry-Time-To-Die) was successfully created.

An index on the attribute 591267 (msDS-Site-Affinity) was successfully created.



Any ideas as to what might be going on, and/or what I can do to get AD installed and working on the new W2K3 box?

I spent a day trying to link in a 2003 server to a 2000 domain which a colleage ran Adprep and eventually restored system state to the 2000 servers. I then started again running ADprep and all ran ok. The second time I linked the servers on a temporary switch which prevented users getting on. I wonder if this is you problem.

Ok, quick update on the fix for this issue, in case anybody else encounters it.

I turns out that the version of ADPrep.exe that is in the I386 directory of Disc 1 of the Windows Server 2003 R2 installation media upgrades AD to version 30. However, Windows Server 2003 R2 uses version 31 of AD, which is why I was still getting the "incorrect AD version" error messages when trying to run DCPromo.

The fix: on Disc 2 of the Windows Server 2003 installation media there is a newer version of ADPrep.exe that upgrades to version 31. I ran this ADPrep, and the DCPromo on the W2K3 server ran with no errors. The newer version of ADPrep.exe is in the \CMPNENTS\R2\ADPREP\ directory on Disc 2.

Here's a link to the article where I learned this information:

P.S. - also, it turns out that the error messages I cited in my original post are expected in this upgrade, and can be safely ignored.
