Error connecting to server, open pipe failed (can't connect to the NetApp Filer)

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

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

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

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.
