5 Common Remote Desktop Errors and How to Fix them

Remote desktop connections are now fairly reliable, and yet there are occasional difficulties here too. In this post, we are going to show you tips and solutions to the five most common remote desktop errors.

These remote desktop errors are defined as follows:

1. Failure of The Underlying Network

One of the most common remote desktop errors and problems is the failure of the underlying network. To check the network connection, you can simply plug a laptop or any device with a bash or command line function into the network connection from which the user is trying to connect.

You can then use the ping or traceroute tools to find out whether there is even a connection to the host or to the relevant network component. Note, however, that this connection test only works if the firewalls allow ICMP (Internet Control Message Protocol) packets.

If the user connects via VPN (Virtual Private Network) or Terminal Services Gateway, the problem could also be with the user's computer. The VPN, gateway or remote desktop infrastructure are also possible causes of the remote desktop errors.

With these types of remote desktop problems, you may need to eliminate one possible cause at a time in order to get to the real problem. For example, you could establish a connection via VPN with an appropriately configured client computer and a securely functioning user account in order to test the remote desktop connection. Troubleshooting is easier here because you can get help from your ISP to check the network connection to solve the remote desktop error yourself.

2. Problems With The Firewall

It is often forgotten that the firewall can also be a problem cause in connection with remote desktop connections. However, this is far more common than you might think.

First of all, you should make sure that the port used by the remote desktop infrastructure is open on all firewalls. Otherwise, of course, no connection between client computers and the server is possible.

The story gets tricky when you have to configure multiple firewalls. For example, the Windows firewall could run on the server and client. There may also be multiple hardware firewalls between the two systems. The port that should be open also differs between the various VDI ( Virtual Desktop Infrastructure ) products. If you are using a Remote Desktop Protocol ( RDP ) based tool, the default port is 3389.

You can also establish a network tunnel that can go through all the firewalls and enable the seamless connection between the two devices more easily, although to do this you would have to need a proper understanding of network connections in general and your own computer network in particular.

3. Problems With The SSL Certificate

Security certificates can also cause problems with remote desktop connections and cause some remote desktop errors. Many VDI products use Secure Sockets Layer (SSL) encryption to secure sessions for users outside the network perimeter. VDIs are Virtual Desktop Infrastructure like Citrix that enable having a remote desktop being hosted as a virtual machine in a server. However, you need certificates to use SSL encryption. With remote desktops, problems can arise in two places.

If the remote desktops want to connect via SSL, they have to trust the certification authority that issued the certificate. This is usually not a big deal for companies if they have obtained the certificate from a large and recognized certification body. However, clients do not always trust the certificates that a company creates in-house. So you should use an authorized certification authority so that the remote desktop connection is also securely successful.

The client must also be able to verify the certificate used by the server. This process may fail if the certificate has expired. It can also be problematic if the name of the certificate does not match the name of the server. So make sure that the certificates are up to date.


4. Network Level Authentication

A specific problem affects Windows Server 2008 R2. Microsoft's Remote Desktop Services uses a security function called Network Level Authentication.

The idea is that the session host must authenticate the user before a session is created. Network-level authentication not only improves security, but also reduces the VDI resources consumed by the session.

This network level authentication can prevent connection problems with remote desktops during a session. However, not all remote desktop clients necessarily support this function.

If you are using Microsoft clients, you can easily find out whether this authentication is supported at the network level. To do this, click on the function icon at the top left in the remote desktop connection menu and then on the About menu item. The client will explicitly inform you if Microsoft's Network Level Authentication is supported.

If the client does not indicate support for this, you can either update the client component or disable the need for network level authentication on the VDI servers. Keep in mind, however, that Network Level Authentication is sometimes activated via the group policy settings.

5. Insufficient Capacity

However, problems with remote desktop connections could also arise when the capacities of the infrastructure are exhausted or fully utilized. Maybe you just don't have enough virtual desktop licenses? These can all contribute in accumulation of some remote desktop errors major and minor ones.

Some VDI implementations also refuse to connect to clients when the server is excessively busy. This also applies if starting another connection would have a negative impact on the performance of existing sessions.

Most of these remote desktop connectivity problems are easy to prevent with a little planning. So make sure that the SSL certificates are up to date, configure the firewalls appropriately and simply keep an eye on the capacity and performance of the VDI environment.

Remote Desktop has many errors and problems but most can be fixed easily. Although it is one of the most risky platforms for remote desktop connection but it is free for windows users and it’s used almost in any network that exists today. So learning to fix these errors can be a good move in the long run. We hope you have learned some new information on how to resolve remote desktop errors in the future.
