Cannot register laptop to DNS when connected via Forticlient - interface is unknown

Hi,

This happens for all our fleet.

On windows7  using Forticlient 6.0.9, when connected over SSL VPN, I cannot register the laptop to the DNS server.

C:\WINDOWS\system32>ipconfig /registerdns

Windows IP Configuration Registration of DNS records failed: The interface is unknown.

Has anyone faced the same issue ?
