Description
When connecting to a RDP Remote Desktop Session from the Desktop Client or Web Client, an error message is produced "Because of a protocol error detected at the client (code 0x2104), this session will be disconnected. Please try connecting to the remote computer again." -
Cause
Port 3389 may be blocked between Safeguard's X1 network port and the destination server. -
Résolution
Test using Safeguard's Telnet test to confirm that communication on port 3389 is not working.
Steps to find the Telnet test within Safeguard's Desktop Client:- Click Administrative Tools
- Click Settings
- Click Diagnostics found under Appliance.
- Enter in the IP address for the destination server, enter port 3389 for RDP, and select Sessions (X1) for the connection.
If the Telnet test does fail, network routes will need to be investigated within the network infrastructure.
