System Center Orchestrator 2012 Beta is not supported on a domain controller:  Currently Installing System Center Orchestrator 2012 on a domain controller is not supported. This is known issue for Beta  release and it is because of different ProductType for domain controller, which Orchestrator Installer does not check for. This is already release noted, please see http://technet.microsoft.com/en-us/library/hh204684.aspx

Running Orchestrator 2012 on domain controller is not recommended for running in production environment, however you can use the below workaround to use in lab environments

Workaround:

Change the ProductType to ServerNT before install and then change it back to LanmanNT after the install

  1. Go into Regedit
  2. HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\ProductOptions\ProductType
  3. Under ProductType take a look at what the Data value is and write that value down.  If it is LanmanNT change it to ServerNT.
  4. Save and close.
  5. Run the install
  6. Once it finishes go back into Regedit and change this value back to its original setting so you do not run into any other issues with other software that may be looking for the LanmanNT.

Details:

As part of the OS requirement check, Orchestrator Install  is checking for “HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\ProductOptions\ProductType” to determine if the OS is Windows Server 2008 R2 or Windows 7 (for designer), basically checking if it is WINNT or ServerNT product type.

If the OS is a domain controller, the  pre-requisite check fails because it’s neither WINNT nor ServerNT.

ProductType for different Windows SKUs

1. WINNT – Windows 7

2. ServerNT – Windows 2008

3. LanmanNT – Windows 2008 with Domain Controller role enabled
