SCOM2007/2012: Momadadmin change

The companies which use AD integration for assigning agents to the correct servers in SCOM use the tool momadadmin.exe which is provided with the Operations Manager source files  to prepare active directory for agent assignement.

There is a small change in how the commandline needs to look like compared between SCOM 2007 R2 and SCOM 2012 RTM.

SCOM 2007 R2:
momadadmin2007

Usage: MomADAdmin ManagementGroupName MOMAdminSecurityGroup {RootManagementServe
r | RunAsAccount} Domain
Also look at: System Center Operations Manager 2007 Unleashed page 387.

SCOM 2012:
momadadmin2012

Usage: MomADAdmin ManagementGroupName MOMAdminSecurityGroup RunAsAccount Domain
Also look at: http://technet.microsoft.com/en-us/library/hh212738.aspx

A lot people perhaps used the root management server in the past to assign permissions to the OperationsManager folder in AD. In SCOM 2012 you can only enter a RunAsAccount to assign permissions to the OperationsManager folder in AD. So select the appropriate account – if you do not use the server action account then enter the account which you have defined in the “Active Directory Based Agent Assignment Account” profile.

If you upgrade from SCOM 2007 R2 to SCOM 2012 RTM then remember to check the permissions in the OperationsManager folder in AD or recreate the folder with momadadmin so that correct permissions are set.
