I perform an upgrade of SP from WSS SP2 to SPF 2010 SP1.
In WSS SP2, I was able to update the farm administrators. In SPF 2010 SP1, I keep receicing the following in the ULS logs:
Local administrator privilege is required to update the Farm Administrators' group.
- I have tried multiple accounts. All with the same error message.
- I have also ran the updatefarmcredentials command. Still same error.
I was able to resolve this issue after running the SP Products Configuration Wizard several times.
Also, currently MS does not support installing SharePoint 2010 on Windows Server 2012. These issues I am noticing could be the result of unsupported environment.
Update: MS is now saying the installation of SharePoint 2010 on Windows Server 2012 will be supported once SP 2010 SP2 is released. Reference
