The identity of the remote computer cannot be verified RRS feed

  • Question

  • Hi, I migrated to SBS 2011 and now when I use RD for any pc , including SBS I receive "The identity of the remote computer cannot be verified. Do you want to connect anyway?" I know that it is something about certificates, but I don't know what . Can anyone give me advice what to do ? Thank you .

  • Answer is enhanced security features from windows vista and above OS . There are workarounds possible if you do not want this warning message to show up but "this will be a decrease in security so should only be changed if you are aware of the what and why of this change."

    Remote Desktop Connection 6.0 prompts you for credentials before you establish a remote desktop connection

    Also:

    This problem occurs because the RDP 6.0 or later  client requires server authentication and when accessing a server via the internet, the Remote Desktop server cannot verify its identity to the client without using a Certificate.

    The solution is to use TS Web Access in Windows Server 2008 and sign the RDP files using RemoteApp Manager or rdpsign.exe command-line tool. Using the Remote Desktop Web Connection tab on the TS Web Access page will always prompt, even if the RDP files are signed, so to provide a standard connection to users that will be signed, install TS Web Access on the Remote Desktop server and click on the following check box:

    Show a remote desktop connection to this terminal server in TS Web Access

    This will create a signed RDP file listed under RemoteApps that will connect back to the same server.

  • I am not sure what advice you have asked for. Why is this prompt showing up or you are not able to connect after you click OK on

    "The identity of the remote computer cannot be verified. Do you want to connect anyway?"
