I’ve been trying to add a WS 2008 R2 DC to our WS 2008 test Active Directory for a little while now. A Microsoft PFE suggested checking the fSMORoleOwner attribute in the ForestDNSDomains and DomainDNSDomains partitions to make sure that they match the actual Infrastructure Master.

For example:

PS C:\> netdom query fsmo
Schema master- - - - - - - - - - - - - - - DC1.domain.tld
Domain naming master- - - DC1.domain.tld
PDC- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -  DC2.domain.tld
RID pool manager- - - - - - - - - - - DC2.domain.tld
Infrastructure master- - - - - -  DC3.domain.tld
The command completed successfully.

To check the value of these attributes you will need to add the partitions to the- ADSI Edit tool.

  • Open ADSIEdit as an Administrator
  • Right-click ADSI Edit at the top of the snap-in and select Connect to…
  • In the Connection Settings dialog box:

  • Enter “ForestDNSZones Partition in the Name field
  • Enter “dc=forestdnszones,dc=domain,dc=tld in the Select or type a Distinguished Name or Naming Context (Be sure to replace “dc=domain,dc=tld with the proper string for your environment)

  • Click Ok
  • Right-click ADSI Edit at the top of the snap-in and select Connect to…
  • In the Connection Settings dialog box:

  • Enter “DomainDNSZones Partition in the Name field
  • Enter “dc=domaindnszones,dc=domain,dc=tld in the Select or type a Distinguished Name or Naming Context (Be sure to replace “dc=domain,dc=tld with the proper string for your environment)

  • Click Ok
