Adprep Fails on Windows 2003 Server
Hello,
I was with one of my customer who wanted to introduce Windows 2008 Server in his existing Windows 2003 Infrastucture for the transition. The scenario was he had
DC01 Windows 2003 Standard Server with all FSMO Roles
DC02 Windows 2003 R2 Enterprise acting as ADDITIONAL DOMAIN CONTROLLER.
So while sitting on the schema master I ran the command Adprerp /forestprep . As per the technet article but I ended up with a following error.

To resolve the issue i again transfered all the roles from Windows 2003 Standard Server To Windows 2003 R2 Enterprise which was acting as ADC and resolved the issue but as a matter of fact if you see the log care fully, when I was running the command from the Windows 2003 Standard server which was holding schema role it was contacting Addional Domain Controller Which was Windows 2003 R2 Enterprise You know why it was contacting ??

Remember When you were introducing Windows 2003 R2 in your env you would have done adprep /forestprep as well which has eventually updated your schema to objectVersion to 31.
The same thing when I was trying to run adprep /forestprep for Windows 2008 introduction its was looking for the schema master server which was having highest objectVersion in my case it was windows 2003 r2. Thats the reason It was contacting Addtional Domain Controller which was Windows 2003 R2.
Note: Please see the attached Jpg below for the screen shot, I have removed the domain name from the screenshot in order to protect the privacy of the customer.
