i have made below changes. i am able to start the VMware VirtualCenter Server service but unable to login with admin account.
I have just edit the vpxd.conf located in C:\ProgramData\VMware\VMware VirtualCenter\
from
<sso>
<enabled>true</enabled>
to
<enabled>false</enabled>
other than VMware VirtualCenter Server service not able to start any vmware services.
below is the windows event log.
The vCenter Single Sign On service terminated unexpectedly. It has done this 390 time(s). The following corrective action will be taken in 60000 milliseconds: Restart the service.
Have you checked the sso logs under may be not able to ping to ? is there any change with RSA database of vCenter 5.1?
Have you tried to restart the SSO service? Used to be a know issue in 5.1
