Hey Chris, we're running the latest and greatest you can download from the MS volume licensing site. We also figured this out working with MS on the phone yesterday. I have reviewed the setup documents, but don't remember this step being in them.
In a 1 server test enviroment we had no issues, but when we setup a 4 server production enviroment, the issue manifested. On the MOM server, you have to reconfigure the logon account for the "Microsoft Forefront Client Security Management Service" from Local System to the Service Account. In a 1 server setup, Local System works, but not in a 4 server setup where your One Point DB is on the Collection Server.
Thanks for posting tho and I hope our solution will help some others from burning a call to MS. We are still having issues with all systems being reported in the FCS console and will continue to work with MS today.
