Re: Error 64, File Server Cluster

We were having similar problems with a couple of clusters with Dell/EMC san

If you find a solution be sure to post, as will I.

Well unfortunately we are using a DAS storage array rather than a SAN,
and it is using MS's built in SCSI drivers. I have already updated
the NIC drivers to the latest, but still no luck.

with many thousands of sub-folders and a very deep tree structure is being
accessed. ??
