Windows Server 2008 Cannot connect remotely

After the Server R2 is configured in turn, the reboot discovery is always Remote Desktop and not connected at all. The specific phenomenon is as follows:

• Occasionally, you can connect to the server through a desktop remote connection. Think it is a firewall problem, various settings-even shut down, still can't connect. Repeated restarts, only a certain section can be connected. But restarting is not a panacea, and the success rate is accidental and low.
• You cannot ping the server, even if you add ICMP to the firewall and configure the Remote Desktop client together. After setting up, the server can ping the other nodes of the LAN (including the remote to the server PC).
• Once you add a wireless LAN service, you can occasionally be on the server remotely, and it's not a solution.
• Even if the connection is occasionally successful, you cannot successfully connect again after disconnecting.

I'm sorry, I really can't. After the most recent restart, connect to server. Keep it up, because it's going to work. Later, it was unable to connect again, then the connection was interrupted and could not be connected again. After a few days of inadvertent thinking, consider deploying the remote Router and access Service (Routing and Remote Access services) in server. The RAAS service binds the network card service and turns on the Nat,ipv4 forwarding service. On this server, Raas is bound to a wired network card. Could it be the cause of the RAAS service that caused Windows Server to not connect remotely? There are so few phenomena that make suspicion.

1. The host provider's server failed to telnet after deploying the Raas service.
2. After the local server restarts, a successful connection can occur, which may be the RAAS service has not yet started.

When you try to shut down the RAAS service to the server, the Remote Desktop Connection succeeds immediately-in the case where the last connection was unsuccessful and there was no reboot.

Possible reasons for the RAAS service, especially the RAAS network adapter that is bound to the remote connection.
