Resolution

Identify the affected products for this issue.

The RealPresence Resource Manager (RPRM) will continue to work when secure Netlogon is enabled in Microsoft Active Directory domain controller.

In RPRM 10.3 or higher, from the Web UI, go to:

  • Admin -> Directories -> Enterprise Directory
  • Set “Select SMB to connect with the Domain Controller” field to SMB 2.0 and Click Update.

Products running version older than 10.3 will need to upgrade to 10.3 or higher in order to set RPRM to use SMB 2.0 to connect to Domain Controller.
