What causes iPad RDP client error code 0x104?
Sometimes, we may encounter RDP error code 0x104 on Mac or iOS devices when trying to remotely access Windows PCs. There are five common causes of iPad RDP client error code 0x104:
- ✍ Remote Desktop not enabled. Make sure that Remote Desktop is enabled on your computer. If not, you may not be able to establish a connection.
- ✍ Network Discovery has been turned off. If the network discovery option in your Sharing settings is disabled, this could be the cause of the error message appearing.
- ✍ Windows Firewall blocks 3389 port. For RDP connections, Remote Desktop uses the 3389 port by default. You will not be able to create a connection if Windows Firewall is blocking it.
- ✍ DNS Settings. If you are using any custom DNS servers, the issue might be rising because of that.
- ✍ RD Client error. The problem may also be on the iPad side, so what you need to do is to uninstall and reinstall RD Client.
