Re: How do I open Port 3389
This is a bit weird problem. You said that RDP is working on your entire network but the same is not working on 2 workstations only. So it is recommended that you must verify the clients properly. I am sure that there is some antivirus application which is causing the failure. Go on those client system and verify the ipconfig. Ensure that they are connected and active. Going from scratch installation is one of the best option that you can try and I am sure it is going to help you in many ways.

There are some registry modification that I want to provide you but it is better if you test that on some other machine. Creating a separate configuration only for 2 clients is not a a valid solution. It is necessary that they would accept the same settings that all other clients had accepted. There are set of third party software that you can try out for remote connectivity.

There is a link below that has number of options available to troubleshoot the problem related to remote desktop connectivity. There are set of common issues that you must follow to fix the problem. The remote desktop wizard is another way to create a new configuration but if your system fails to find the active system on the next end, then you have to ensure that both systems are able to discover each other. Check out the link for more info.

This issue is common on those server which has 2 NIC setup. You can rerun CEICW and then check out the firewall configuration. CEICW is one of the easiest way to work on sbs and configure different type of settings. Update the lan drivers for client system and verify the same once again. I am sure it will help you. Firewall configuration is required to work with number of different systems or else failure is more common.
