I was able to create my IPAM GPO's for my root domain, but all my child domains are failing with the following error.  Environment:

IPAM: 2012 R2
Domain Controllers: Mix of 2008, 2008 R2, and 2012 R2.

PS H:\> Invoke-IpamGpoProvisioning -domain child.domain.local -GpoPrefixName IPAM-CHILDDOMAIN -force -DomainController dc01.child.domain.local -IpamServerFqdn ipam.domain.local

Hi Mark,

Can we successfully deploy IPAM by creating these GPO manually?

Which user do you use to run this command? Please try to run this command with the Administrator of the subdomain.

Beside, if it is possible, could you please post the screenshot of this error?

Best Regards.

I have run as an enterprise admin in the root domain and as a domain admin in the child domain - same result each time. The text of the error is included below:

PS C:\Windows\system32> Invoke-IpamGpoProvisioning -domain child.domain.local -GpoPrefixName IPAM-CHILDDOMAIN

Confirm
The Invoke-IpamGpoProvisioning cmdlet creates and links three Group Policy Objects in the domain indicated by Domain parameter, for provisioning IPAM access settings on the servers that are managed by IPAM. The cmdlet also modifies the domain wide DNS ACL to enable read access for IPAM. The value of GpoPrefixName must be the same as the one provided in the IPAM provisioning wizard when selecting the option of Group Policy Based provisioning.

You have not specified the optional parameters DelegatedGpoUser or DelegatedGpoGroup. The delegation parameters can be used to enable IPAM GPO edit privileges for users or groups who do not have domain or enterprise administrator privileges, but need to mark servers as managed or unmanaged in IPAM. Do you want to perform this action?
[Y] Yes  [N] No  [S] Suspend  [?] Help (default is "Y"): y

Did you ever figure this one out? I am getting the exact same error and I can't find anything online regarding this issue.
