DTrace of EVIndexAdminService shows failures as below:

(EVIndexAdminService)    <2364>    EV-L    {IndexAdminImpl} Entry - ValidateIndexSnapshotLocationPath(). Validating path '\\SnapShotServer\SnapshotFolder' for Enterprise Vault index server '1DCE5CDE53BDA9441A4EC0233FCED5CAD1410000evserver1'.

(EVIndexAdminService)    <2364>    EV-L    {IndexAdminImpl} Exit ValidateIndexSnapshotLocationPath index snapshot location path is invalid.

The issue occurs as EVIndexAdminService tries to ping the remote location to test the connectivity. If the ping to the remote server fails, the validation will be aborted.

This issue has been addressed via a code change and is fixed in EV 14.4.2, EV 14.5.1, EV 15.0 and later versions.
