Resolution

add below content into /etc/hosts
127.0.0.1 <fqdn of vda>
::1 <fqdn of vda>

Problem Cause

VDA fqdn missing under /etc/hosts.
LVDA queries the AD with the hostname value found for 127.0.0.1 entry in /etc/hosts to find the Computer SID of the LVDA.
If LVDA cannot find a Computer Object in AD with dnsHostName equal to the hostname value found for 127.0.0.1/::1 then it will and fail to find Computer SID of the LVDA and registration will fail with "Get ComputerSID Failed" error.
