Windows Server 2016 - No ethernet connection after activating Routing and RAS for VPN RRS feed

  • Question

  • Hi everyone, I hope you are doing well.

    for the past few months, our clients have been using the Routing and RAS service to access our windows server 2016 via VPN. The VPN service has been configured as described in https://www.starwindsoftware.com/blog/how-to-install-vpn-access-on-windows-server-2016.

    Since last week, we are having problems with the Routing and RAS service: The server has not been reachable anymore as the network/ethernet connection broke. After a restart, the server is reachable again - but only until the routing and ras service starts. We have tried several settings in the Routing and RAS configuration but nothing worked for us. The only way to get everything working again, was to deactivate, delete and re-configure the routing and ras service with multiple restarts in between. After that, the server connection + vpn service works fine again. After ~8 days, the exact same problem occurred again.

    The event log does not show any anomalies. We only have one NIC (if this information is important). The network configuration, however, shows that whenever the problem occurs, the RAS Dial interface is not showing up as usual (in the success case):

    PPP-Adapter RAS (Dial In) Interface:

    Verbindungsspezifisches DNS-Suffix:
    Beschreibung. . . . . . . . . . . : RAS (Dial In) Interface
    Physische Adresse . . . . . . . . :

    Standardgateway . . . . . . . . . :
    NetBIOS über TCP/IP . . . . . . . : Aktiviert

    Do you have any idea what could be the reason for this problem and how we could fix it?

    Best Regards
