    Windows RDP connection to server working unstably

    Hello there
    I am here today to ask about some wierd stuff going on with rdp and remoteapp connections to my server at home. The things is that half of my computers connect, and the other say "wrong credentials please try again" when I enter the same credentials that work. This only started happening recently. I have a server 2008 r2 server that I am connecting to. Now here's where it gets deep. When I use a third party rdp client on the non-functioning machines, the authentication works fine. When I set up a brand net VM on the non working computers, it works fine too. Also whenever I disable the windows security dialog in the rdp file properties and enter the credentials on the server once the connection has been established, it will start properly too. Why is it somehow blocking the windows security dialog. I deleted my saved credentials and I do not want to enter them every time thats why I saved them. You cannot save credentials using the connect-first-then-authenticate method. PLEASE HELP as I am using this server a LOT and having it acting wierd like this is annoying. I already rebooted the machines. Everything is fine on the server side.

    It almost sounds like a time issue. Authentication will fail if the time between source and destination is too far off.

    Verify BOTH the time AND the timezone on the machine that you are connecting from and the machine you are connecting to are accurate.

    I may be completely wrong with this, but it's something I've encountered a few times and worth checking.

    I would suggest running a VPN in conjunction with RDP.
