Technical Articles ID: KB68524
Last Modified: 10/8/2021

Environment

McAfee Endpoint Security Storage Protection (ENSSP) 2.x
McAfee VirusScan Enterprise for Storage (VSES) 1.x
NetApp Filer

Problem

ENSSP/VSES can't connect to the NetApp Filer.

The NetApp Filer NetApp log shows errors similar to the following:

DATE [filerXXX: cifs.pipe.errorMsg:error]: CIFS: Error on named pipe with (ServerName): Error connecting to server, open pipe failed

Solution 1

Add NTAPVSRQ to the list of NullSessionPipes:

Click Start, Administrative Tools, Local Security Policy.
Expand Local Policies and click Security Options.
Scroll down and open Network access: Named Pipes that can be accessed anonymously and add NTAPVSRQ.

NOTE: This value isn’t case sensitive; ntapvsrq is equally valid.
Restart your computer.
Check the logs and verify that the issue is resolved.

If this procedure doesn’t resolve the issue, go to the next solution.

Solution 2

If adding NTAPSRQ to the list of NullSessionPipes hasn’t resolved your issue, enable Network access: Let Everyone permissions apply to anonymous users.

Click Start, Administrative Tools, Local Security Policy.
Expand Local Policies and click Security Options.
Scroll down and double-click Network access: Let Everyone permissions apply to Anonymous users.
Click Enable, OK.
Restart the computer.
Check the logs and verify that the issue is resolved.

If solutions 1 and 2 haven’t resolved the issue, go to the next solution.

Solution 3

Check that the PTR record entry has been created in the DNS for ENSSP/VSES. If it hasn’t, create the PTR record manually and make sure that the NetApp Filer and ENSSP/VSES are in the same domain.
