      I just ran into something similar with Windows 10 connecting to 2012 R2 RDG and having the remember credentials checked. It would not let anyone login after it remembered their creds.

      It requires a registry entry for the client. Not sure if it would benefit you, but here it is.

      reg.exe Add "HKCU\Software\Microsoft\Terminal Server Client" /V "RDGClientTransport" /T REG_DWORD /D "1"

        Not sure if it's related, but I deleted the Default.RDP file from my documents and that didn't fix it either. The posts I got that suggestion said it was related to remembering creds.

            I had been meaning to go back and look at the article from April referencing the credssp cve, but haven't had a chance. According to what others are saying there, any cumulative update for the server from March 2018 and later should have the patch and will allow connections.

                  What version of RDP do you have? I don't have that option.

                  This is what I have.

                    You change it on the device you're connecting to, not the PC you're connecting from.

                        I tested on 2012 R2, it worked there.

                              The fix also fixes virtual machine connection too.

                                Hello
                                in a network with a 2012r2 server after the update to the last customer relationship win10 home / prof. This error appears:
                                can not find the "server01" computer. It is possible that "server01" does not belong to the specified network. Verify the computer name and the domain to which you are trying to connect.
                                which instructions can I follow, in addition to those listed in the discussion as well as update the server, to solve the problem?
                                thank you. regards.0_1528649933636_IMG_6474.JPG

                                      This happens when one system is up to date and the other is not. I ran into this with our Hyper-V hosts because our desktops got updated first. Updating the Hyper-V hosts resolved the issue, as well as other systems.

                                        It's due to MS patching a vulnerability that changes how authentication works. Resolve it by patching, not by lowering your security...

                                          But still the issue with @aginformatica is different as the error is not the one is usually the update issue.

                                            It also looks like @aginformatica is connecting on port 1512 as opposed to 3389...
