How can you manually renew the license for a ProxyAV appliance?
Anti-virus scanning services cannot begin without a valid license installed on the AV appliance from one or more AV vendors. License Key files are obtained from the Network Protection Licensing Portal (NPLP), which requires your Symantec credentials for access.
To acquire a license:
NOTE: If you already have an AV appliance and subscription number, you can enter that subscription number in place of the activation code when you receive a new AV appliance.
If you have any questions, please contact Symantec Customer Care team.
