We have a pair of servers running Windows 2008 (no R2) Enterprise Server using the Cluster. The cluster is running fine for several years.
Today I login to the server using domain account that is in the local Administrators group., I tried to "Validate a Configuration: but it gave me error:
"Failed to validate node 'sp01.nt.local'. An error occurred while determining if you have administrator privileges on 'sp01.nt.local'. Attempted to perform an unauthorized operation. BTW the cluster still running fine.
What did go wrong?
Thank you,
Iwan
