Hello all, I just, today, upgraded one of our Dell Server 2008 r2's to Server 2012 r2 and rebooted for updates and final install. And I did all of this over Remote Desktop. Once all of the updates were done, I was unable to log back in via Remote Desktop. So I physically walked next door and logged in just fine. It shows that RD is checked but I am still unable to access the server from my desktop in my office. I have admin rights and I was found almost immediately when I added my self to the server. The server sees all of the other connected groups locally and otherwise. The Subnet mask and IP's are static and correct.
When, from my desktop, I click on connect to the server it asks me for my credentials, it remembers my log-on ID, but then gives me the error; "An authentication error has occurred. The function requested is no supported."
Also, I have no power options to restart the machine. I went into gpedit.msc and put the rule to disabled to give myself access to the restart and power off options but it does not take. ie: I still have to shut down/restart the server via a cmd line.
The upgrade was pretty quick and I had no extraneous errors or anything. Any ideas I can try?
Thank you in advance for your assistance.
Respectfully,
WME
