EV Search may display the message "Search is returning partial results because Enterprise Vault could not search the whole vault" when searching index locations that are hosted in an Index Server Group.  For this specific issue to occur, at least one of the EV servers within the Index Server Group will have a Windows 2012 NIC Team with a standby adapter configured, together with an additional NIC that is part of a separate network (such as a network that is used for the backup of the server).

Error Message

A dtrace of AuthServer and EVIndexQueryServer will show AuthServer lines indicating that the hostname for the backup network rather than the production network is being used to generate the auth token when running the search:

(AuthServer) <4828> EV:L {CClientAuthIntImpl::RegisterClientIdentity:#829} Completed registration. Token
[backup_net_hostname.testdomain.local T1pW*****], SID count [13], Cancel Id [21144400].

When a Windows 2012 NIC Team is used with a standby adapter configured Enterprise Vault is unable to accurately determine the hostname or IP Address of the production network when it generates its auth token.  Adjusting the binding order of the NIC's does not correct the problem.



Create Hosts file entries on all EV servers in the Index Server Group that resolve the backup network hostname for each EV server to their corresponding  production network IP address.


Delete the PTR record for the backup network hostname from DNS


Set all NIC's in the Windows 2012 team to be active
