I have 3 RDP's (2 of Windows server 2012 R2 and 1 Windows Server 2008 R2). By using Microsft Remote Desktop, I am able to get connected remotely with the two Windows Server 2012 R2. But I am unable to connect with Windows Server 2008 R2. I am getting the below error.
Previously I was able to connect with all three. Also, I want to mention that in the windows environment I am not facing any issue with the RDP.
I am stuck to it and don't know what to do. Any help would be highly appreciated.
I had this issue and this is what I did to get working back the RDP client on a Macbook pro mid-2015 with the last big sure release.
First make sure that :
the remote server IS online
the remote server IS accepting RDP connections
the remote server firewall IS configured correctly with the right port
the remote server IS NOT configured to accept only connections with NLA
After validating the above points, then on your client (the Mac) you can try to get working the RDP with this first step :
remove (please make a backup) the file UBF8T346G9.com.microsoft.rdc located in /Users/[Your username]/Library/Group Containers/ then reboot your Mac.
If it still doesn't work, you could try to remove the app, reboot, then re-install the app again.
You can also analyze the Event-Viewer on the 2008 R8 server to see if there is something to help you to spot the issue.

I faced the same problem some years ago.
here's the solution:
Read the article carefully. https://learn.microsoft.com/en-US/troubleshoot/windows-server/remote/troubleshoot-remote-desktop-disconnected-errors.
And check if the remote server IS accepting RDP connections.
And also check if the remote server accepting only connections with NLA.
delete the file UBF8T346G9.com.microsoft.rdc and Reboot.
And if still doesn't work, then totally uninstall / remove the app and install again and check.
Thank You
How is it possible to overcome connectivity issue from win server 2003 R2 to a Citrix based application hosted on a win server 2008 R2? Short summary of the problem is that while trying to connect from win server 2003 R2, to a certain URL (this goes for all browsers) hosted on win server 2008 R2 (Error code: sec_error_bad_signature).
I just installed a Windows 2008 Standard R2 server with RDS. Whenever I attempt to connect to the server via RDP from a Windows 2003 server, I get the following error.
I am however able to connect from a Windows 7 desktop and using a Linux RDP client.
Anyone know why I'm getting this error and how to resolve the problem?
Thank you in advance.
This is probably a Server Fault question, but none the less my guess is the server has the following setting:
Maybe your Linux RDP client doesn't support this functionality?
If not, check your Firewall, it needs to look like this:
How do I lock down my Windows 2008 R2 Server so only certain computers can connect to it? Ideally it would use some sort of certificates. I've done this in Linux, but I don't know where to start with Windows.
Thanks!
I need help. I wrote simple sink by sample in http://msdn.microsoft.com/en-us/library/ms998610.aspx. On IIS Smtp Windows server 2003 it work fine. But on IIS Smtp Windows Server 2008 or 2008R2 it don't work. I try other sample from Internet. None of them don't work on IIS Smtp Windows Server 2008 / 2008R2. Any idea?
Windows Server 2008 has a newer version of IIS that has full integration with ASP.NET. This is the default mode. You can switch back to the older (ASAPI ASP.NET) by changing the application pool in IIS from "default" to "classic". That should make your app run like it does in Server 2003.
Without seeing more code and details, that's the only thing I can suggest.
