Missing Route

Resolution

To resolve this error message, add the client IPv6 route to the DirectAccess server’s routing table and publish it. This is accomplished by running the following PowerShell commands on the DirectAccess server.

$IPv6prefix = (Get-RemoteAccess).ClientIPv6Prefix
New-NetRoute -AddressFamily IPv6 -DestinationPrefix $IPv6prefix -InterfaceAlias “Microsoft IP-HTTPS Platform Interface” -Publish Yes

Next, restart the Remote Access Management service (RaMgmtSvc) using the following PowerShell command.

Restart-Service RaMgmtSvc -PassThru

  1. Glad they didn’t deprecate DirectAccess on Win Server 2019 yet. 🙂

    • You and a lot of other folks I’m sure! Gives Microsoft some time to get Always On VPN sorted. 🙂

      • Hey Rich, this worked fine on our first DA server but for the second one in the cluster, the route adds but then removes itself when you restart RaMgmtSvc or the server. I can re-publish it but I cant get it to stick.

        Tried using PoSH and netsh, for some odd reason it’s removed when the service reboots, any idea?

      • Thanks for the heads up. Suspected that might happen. I just did some quick testing with a single server and didn’t see any issues. For now you’ll have to keep re-applying the missing route until a fix is available. FYI, Microsoft is aware of the problem and working to address it. I’ll be sure to update the post when it’s available.
