failoverclustering manager 0x80070005

Hi all,

Yesterday I had changed the windows folder permission owner from TrustedInstaller to Administrator together with all the sub folder and files all administrators full control and users read and execute.

after that i try the failover cluster manager, by right it will show the cluster which previously i had created.

then i manually connect the cluster and it show me the error message Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)).

I try to revert back but still cannot , any one can help me???
