In a vSphere 5.5 environment based on 4 ESXi 5.5 servers the vCenter is configured as a Windows Server 2008 R2 VM.
The vCenter VM got corrupted so I restored it from a 2 days old Veeam backup.
After restoring the VM the (restored) vCenter looks unable to communicate with the ESXi servers, mainly 2 of the 4 ESXi servers.
So I can move VMs between two of the 4 server but not to the other 2.
I restarted several times the vCenter with no success.
I cannot power off the ESXi nodes because there are production VMs, and I cannot move them for the above reasons...
How can I force the (restored) vCenter sybchronize with all the ESXi servers?
