In Windows 10 and Windows Server 2012 R2, the .NET Framework 3.5 is a Feature on Demand. The metadata for Features on Demand is included. However, the binaries and other files associated with the feature are not included. When you enable a feature, Windows tries to contact Windows Update to download the missing information to install the feature. The network configuration and how computers are configured to install updates in the environment can affect this process. Therefore, you may encounter errors when you first install these features.

To resolve this issue, use one or more of the following methods. After you complete each method, send yourself a test email message to make sure that you can send and receive messages without receiving an error message. If you continue to receive errors, try the next method.
If the LED is blinking green, this indicates that the device has a network connection, but has not received an IP address via DHCP. If connected to your main network, check to make sure that your router is powered on and has its DHCP server enabled. If the router has any access control/allowed devices/MAC filtering function, either the HDHomeRun needs to be on the allowed list, or this function should be disabled. If the HDHomeRun is directly connected to the network interface on your computer, the interface should be set to a static IP in the 169.254.x.y range (for example, 169.254.1.9) with a subnet mask of 255.255.0.0
This is not necessarily an error. This is simply how the CableCARD asks for itself to be rebooted, which is often necessary for changes made by the cable provider to take effect. You do not need to call your cable provider, as it is normal to see this when they are working with the card, or if a firmware update is done to the card.

The VPN server may be unreachable, or security parameters may not be configured properly for this connection. 801This connection is configured to validate the identity of the access server, but Windows cannot verify the digital certificate sent by the server.802The card supplied was not recognized. Please check that the card is inserted correctly, and fits tightly.803The PEAP configuration stored in the session cookie does not match the current session configuration.804The PEAP identity stored in the session cookie does not match the current identity.805You cannot dial using this connection at logon time, because it is configured to use logged on user's credentials.806A connection between your computer and the VPN server has been started, but the VPN connection cannot be completed. The most common cause for this is that at least one Internet device (for example, a firewall or a router) between your computer and the VPN server is not configured to allow Generic Routing Encapsulation (GRE) protocol packets. If the problem persists, contact your network administrator or Internet service provider.807The network connection between your computer and the VPN server was interrupted. This can be caused by a problem in the VPN transmission and is commonly the result of internet latency or simply that your VPN server has reached capacity. Please try to reconnect to the VPN server. If this problem persists, contact the VPN administrator and analyze quality of network connectivity.808The network connection between your computer and the VPN server could not be established because the remote server refused the connection. This is typically caused by a mismatch between the server's configuration and your connection settings. Please contact the remote server's Administrator to verify the server configuration and your connection settings.809The network connection between your computer and the VPN server could not be established because the remote server is not responding. This could be because one of the network devices (e.g., firewalls, NAT, routers, etc.) between your computer and the remote server is not configured to allow VPN connections. Please contact your Administrator or your service provider to determine which device may be causing the problem.810A network connection between your computer and the VPN server was started, but the VPN connection was not completed. This is typically caused by the use of an incorrect or expired certificate for authentication between the client and the server. Please contact your Administrator to ensure that the certificate being used for authentication is valid.811The network connection between your computer and the VPN server could not be established because the remote server is not responding. This is typically caused by a pre-shared key problem between the client and server. A pre-shared key is used to guarantee you are who you say you are in an IP Security (IPSec) communication cycle. Please get the assistance of your administrator to determine where the pre-shared key problem is originating.812The connection was prevented because of a policy configured on your RAS/VPN server. Specifically, the authentication method used by the server to verify your username and password may not match the authentication method configured in your connection profile. Please contact the Administrator of the RAS server and notify them of this error.813You have attempted to establish a second broadband connection while a previous broadband connection is already established using the same device or port. Please disconnect the earlier connection and then re-establish the connection.814The underlying Ethernet connectivity required for the broadband connection was not found. Please install and enable the Ethernet adapter on your computer via the Network Connections folder before attempting this connection.815The broadband network connection could not be established on your computer because the remote server is not responding. This could be caused by an invalid value for the 'Service Name' field for this connection. Please contact your Internet Service Provider and inquire about the correct value for this field and update it in the Connection Properties.816A feature or setting you have tried to enable is no longer supported by the remote access service.817Cannot delete a connection while it is connected.818The Network Access Protection (NAP) enforcement client could not create system resources for remote access connections.
