Network failure

One of the most common remote desktop problems is a network failure.

To check connectivity, try plugging a notebook into the network port.

The user is trying to connect from and use the Ping or Tracert command to see if it is connected to the host server or connection broker.

However, keep in mind that you can only test remote desktop connectivity.

In this way, if you allow ICMP packets to bypass network firewalls.

If the user or remote desktop connection manager experiencing the problem is connecting remotely through a VPN or Terminal Services Gateway.

The problem may be with the machine. With these types of desktop issues. Elimination will have to be done to diagnose the problem.

For example, try to connect to the VPN using a properly configured client computer and a trusted user account to see if remote desktop connectivity can be established.

Problems with the firewall

It’s pretty easy to ignore the fact that the firewall can contribute to remote desktop connection problems, although it’s actually quite common.

  • To prevent this from happening, make sure that the port used by the remote desktop software is open on all firewalls between the client computer and the server it connects to.
  • The difficulty is that you may have to configure multiple firewalls. For example, Windows Firewall may be installed on both the client and server, or there may be multiple hardware firewalls between the two systems.
  • Also, the port number that must be opened on firewalls differs from one Virtual Desktop Infrastructure ( VDI ) product to another. (If you are using a tool based on the Remote Desktop Protocol ( RDP ), this uses port 3389 by default).

Authentication at the network level

In Windows Server 2008 R2, Microsoft’s Remote Desktop Services is designed to use a security feature called Network Level Authentication.

  • The basic idea is that the session host must authenticate the user before creating a session. Network-level authentication not only improves security but also helps reduce the amount of VDI resources used by the session.
  • Network-level authentication can prevent remote desktop connection problems later in the session but is not supported by all remote desktop clients. If you are using Microsoft clients, you can determine if they support network-level authentication.
  • By clicking the icon for this feature in the upper left corner of the Remote Desktop Connection menu and choosing from the Information menu. The client will explicitly determine if it supports Microsoft Network Level Authentication.

If you don’t see the message that the client supports it. You can upgrade the client or disable the network-level authentication requirement on the VDI servers.

Note that sometimes network-level authentication is enabled through Group Policy settings.

Exceeding capacity

Finally, you may encounter remote desktop connectivity issues if you exceed the capacity of your infrastructure.

Have you run out of virtual desktops or VDI licenses? Some VDI implementations also reject client connections.

If the server is too busy or if launching another virtual desktop session weakens the performance of existing sessions.

These remote desktop connection problems can be prevented quite easily with a little planning.

Make sure the SSL certificates have been loaded, properly configure the firewalls and pay attention to the VDI capability.
