The 5 Most Common Remote Desktop Connection Internal Errors

A client may be unable to connect to a remote desktop session if a communication channel is unavailable. Elimination is the quickest and most efficient technique to identify this problem. To begin, use a client that has previously been able to connect successfully. Finding out if the issue stems from a single user, the network as a whole, or a terminal server/Windows server is the ultimate goal.

  • RDP internal error with firewalls

The idea that a firewall could be a factor in a remote desktop not working is easily discounted, but it happens all the time. RDP traffic is sometimes barred from public networks.

Security certificates might also cause remote desktop connection issues. Many VDI products widely use secure Sockets Layer (SSL) encryption to access VDI sessions from outside the network. SSL encryption, on the other hand, necessitates the usage of certificates, which might present two issues with remote desktop connectivity.

First, if remote desktops are to work, recipient pcs must acknowledge the certificate authority that provided the certificate. For firms that buy their credentials from a well-known source, this isn’t an issue, but clients may be skeptical of certifications that an organization generates itself.

When using a certificate issued by an enterprise certificate authority, network clients will not immediately trust the certificate. For the certificate to be trusted, you will need to download the root certificate from the certificate authority and place it in the client’s certificate store.

As part of the verification process, the client must also check the server certificate. If the certificate is expired or the name on the certificate does not match the server’s name using it, the verification process may fail.

  • RDP internal error with the domain name system

Many remote desktop connectivity issues can be traced back to DNS issues. Clients may not connect to a host if an administrator has modified the host’s IP address.

External DNS servers can potentially cause problems for clients if they are unable to resolve hosts on the private network of the company they are connected to.
