Problem

When you copy folder/files from a network snapshot to the current location over the same share, you see the following error:

McAfee Endpoint Encryption

Fatal Error
 

The driver trace log records the following error:
 
FFFFFA80048C6B60:0 07:32:17.531 SbCe!Ce_pre_operation_network_query_open
(cecreate.c:4646): RFO: FFFFF880072995C0 Failed to locate encrypted file:
00000000 Name \??.???\??dfs\K-P\PE\5431\Users\Username\B6
 

When the DFS network share is configured with backend storage on NetApp or Checkpoint; the snapshots can be configured on both NetApp and Checkpoint servers and can be accessed with redirectors:

  • Actual location: \\CONTOSO.com\dfs\eeff
  • Using NetApp redirector for snapshot : \\CONTOSO.com\dfs\~snapshot\nightly.0\eeff
  • Using Checkpoint redirector for snapshot : \\CONTOSO.com\dfs\.ckpt\nightly.0\eeff

You see this issue whenever you copy a file from the snapshot location to the current location. For example, copying from \\CONTOSO.com\dfs\~snapshot\nightly.0\eeff\test.txt to \\CONTOSO.com\dfs\eeff\restore.

NOTE: You see this issue only when both server and client systems are using Server Message Block 2 (SMB2). Therefore, this issue is only applicable to Windows 7 systems.

Workaround 1

Do not copy the files directly between the DFS shares. Instead, copy them from the first DFS share (path 1) to the Windows 7 client, then copy them from the client to the second DFS share (path 2).

Workaround 2

Copy the files from snapshots to current location using command line Copy.
