NetApp 7-mode activity monitoring is not working when the SAM agent is installed on Windows 2019 machine

Summary​

Summary: NetApp 7-mode activity monitoring is not working when the SAM agent is installed on Windows 2019 machine

Issue​

Issue: You are attempting to monitor NetApp in 7-mode via a Netwrix Activity Monitor agent running on a Windows 2019 machine. When trying to use the Connect button during configuration setup, you see messages about a being unable to open a TCP session or certificate error. Note that other issues can also cause the certificate error. Try with the HTTP ignore certificate errors option. Communication from the agent to the NetApp cannot be established, so scanning is not possible.

Instructions​

NetApp 7-mode by default requires the SMB1 protocol. Windows 2019 by default disables SMB1 protocol. The preferred method to resolve this issue is to enable SMB2 communication on the NetApp device by using the following setting in the NetApp configuration:

options cifs.smb2.client.enable on

This method is the most secure.

Alternative (less secure):

  1. Enable SMB1 on the Windows 2019 machine.
  2. Restart the SAM agent.

Note: Enabling SMB1 on Windows 2019 is less secure and is not the preferred option.
