Can't join Server 2008 R2 RODC to SBS2008

Answers

  • Hello,

    assure to use adprep.exe to run the command, as SBS 2008 is ONLY available as 64bit version.

    And please post the output from "dsquery * cn=schema,cn=configuration,dc=domainname,dc=local -scope base -attr objectVersion" without the quotes in a command prompt.

    It should provide you the schema version 47, if 44 is shown the schema is NOT prepared for Windows server 2008 R2 instead for Windows server 2008.

  • In order to add RODC in windows 2008 R2 OS, you need to prepare your environment first using ADprep tool. There are two version of the adprep tool located inside windows 2008 R2 media one is 32 bit i.e adprep32.exe (To be used only on the DC containing 32 bit OS)& other is adprep.exe(To be used only on the DC containing 64 bit OS).

    Considering you are running windows 2008 32bit OS, you need to use adprep32.exe located inside windows 2008 R2 media & then copy or run directly by locating adprep32.exe tool on the cmd. The cmd is adprep32 /rodcprep. There is no harm running adprep /rodcprep & its not going to have any kind of negative impact to your environment, it will only prepare your environment for the additon of RODC.

  • You need to prepare the domain to install RODC in the enviroment.You need to insert win2008 R2 DVD on Win2008SBS  server and run adprep /forestprep,adprep /domainprep /gpprep & adprep /rodcprep.

  • Hi,

    Checked my schema and yes it was at 44, ran adprep from the R2 media and upgraded to 47 now. RODC can now connect and join the domain.

    Thank you

  • Thanks for assistance, mainly confirmation that I need to run R2 media which the links (that I also had) don't mention so I was only getting it to 44 and not 47 which I guess is the minimum the R2 server can do.
