Do I *really* need a Service Connection Point in AD to complete a Project Server 2010 SP2 installation?

Hi all,

I have installed Project Server 2010 SP2 and run psconfig.exe

PSCONFIG is failing because it cannot set up a Service Connection Point in AD. I've checked in AD and the contains 'Microsoft SharePoint Products' does not exist. All the resolutions I can find suggest adding the container into AD.

The issue I have is that I have no control of the AD, and adding containers will take lengthily negotiation.

Is there any way of completing the installation and getting my site back without adding the container into AD?

Thanks in advance.
