How to disable SMB2 enforcement

SUMMARY

Disable SMB2-only enforcement to allow Sharepoint backups, Oracle backups or Hyper-V Instant Recovery

ISSUE

Unitrends provides regular security patches to address vulnerabilities as discussed in Unitrends Response to certain security vulnerabilities (CVEs) - Reference Article.

As part of these security patches, the Unitrends system can be configured to only allow SMB2 access however certain applications are not fully functional when using SMB2.

Currently, the following application features do not allow SMB2 support:

  • Hyper-V Instant Recovery
  • Sharepoint application protection
  • Oracle application protection

RESOLUTION

To revert from SMB2-only, run the following commands:

security_option smborig
security_chk
