Hi all,
I have a lab environment that is Windows 2008 R2 and Windows 7. I am migrating all my servers and clients to Windows 2012 and Windows 8. As this is a remote lab environment I rely on Remote Desktop Gateway to access the lab.
I have created a new Remote Desktop Gateway server with only this role assigned. It's configured exactly the same as my Windows 2008 R2 server. Certificate works and when browsing to domain.com/rpc I am asked for credentials. Upon entering I get
a blank screen which is expected.
I have tried removing all CAP and RAP policies and then exported the ones from the working 2008 server into 2012 but I still see the same error. Yesterday I did get this working. I deleted the CAP and RAP polices and recreated them manually. They immediately started working. Thinking this was now solved I uninstalled the UI to turn the server into core. After the reboot though I was back to getting the same error. I put the UI back on and rebooted but again no
matter what I tried it does not work. Eventually I gave up and reinstalled 2012. The issue though still persists. I am now out of ideas and back to using the to be replaced 2008 R2 server which works fine.
My policies are set to allow DOMAIN\Domain Users to access any computer on the network on port 3389.
I can see the authentication hit the DC and be a success. The only failure is the one logged on the RDG which is this...
