Sophos NAC Advanced: The NAC Agent can fail registration during an upgrade even when the NAC application server is in maintenance mode.
NAC Agent registration will fail during a Sophos NAC upgrade if the NAC Agent is registering for the first time. The NAC Agent registration failure occurs even if the NAC application server is in maintenance mode.
What to do
There are two workarounds:
- Prior to placing the NAC application server in maintenance mode, access the Sophos NAC Web interface, select Configure System > Agent Registration, and select the Once option button. Complete the NAC upgrade. Once the upgrade completes, change the Agent Configuration setting back to its original setting.
- When the NAC Agent fails to register, click Check Compliance on the dialog box containing the registration error. This resolves the error.
