Internal Reference: Fetching Saveset for indexing
This issue is due to Lanman settings in VCS. The erroring process is attempting to access or reference a part on a partition on another Enterprise Vault Server and is unable to. In the event ID 6882 above we can see that the process is attempting to access a file on another cluster's partition (i.e. \\EVCluster3\EVPartition01d70baa13838070$). Attempts to access the partition outside of EV also fail. For instance from \\EVCluster1 attempting to browse to \\EVCluster3\EVPartition01d70baa13838070$ or any administrative share on EVCluster3 fail in a similar manner through Windows Explorer.
