Microsoft offers remote desktop users a proprietary network protocol, the Remote Desktop Protocol (RDP). This protocol is the terminal services control tool (Remote Desktop Services) and is responsible for executing remote desktop commands.
RDP controls both the server terminal and the client and regulates the transfer of the contents of the screen and the keyboard and mouse inputs over the network. It is not essential to have a version of Windows for the server.
Windows remote assistance support is a possible variant for achieving remote desktop access in Dell PowerEdge R240 that offers users the possibility to invite people outside their systems, which takes place, above all, in remote maintenance sessions in the that technicians intervene in a local network and carry out repairs in the software or adjustments in the system.
- First Step: make sure that support for remote assistance is activated. You can access the path Control Panel> System and Security> System> System Properties> Remote ( Control Panel> System and Security> System> Remote Access Settings ). To authorize remote assistance support, select the corresponding box.
- Second Step: to invite an external user, open the wizard and enter “MSRA” in the search field or follow the path Start> All programs> Maintenance> Windows remote assistance ( Start> All programs> Remote aid). In the window below, you can choose to ask for or offer help. In the case of the first option, click on “Invite someone you trust for help”.
- Third Step: now you can send an invitation (ticket) to the guest user. For this, Windows offers you three possibilities:
You can save the invitation file on your computer and upload it as an attachment in an email.
Your email program opens automatically, and the file can be sent directly to the recipient.
You can use the “variant Easy Connection” (Easy Connect) to bypass email traffic. With the invitation, the external user also receives a password to authenticate in subsequent remote desktop access.
- Fourth Step: once you get the password, the guest user can now connect to the remote computer using Dell PowerEdge T340. However, access to connections over the Internet may be denied because the file hosts the local IP address. Therefore, this user needs either his external IP or his DNS name, which can be established through dynamic DNS services.
- Fifth Step: the external user must enter the password provided in the viewing window.
