Locked out domain Administrator account, or...

Hi,

I have one distant office to maintain, out of the country, few hundred kilometers away. As there were no problems, I did not connect to that server via RDP for few months. Today they called for some change to make, a 5-minute simple administrative task.
But I cannot connect remotely anymore!

With "DOMAIN\Administrator" account, my login is simply rejected each time, saying username or password is not correct. But it is! I am the only admin and this is the only admin password.

Just in case, I always setup a spare domain admin user with full rights. But I was not able to connect with this user either! I get this error:

The remote session was disconnected because there are no remote desktop license servers available

I have access to remote computers via TeamViewer, I have access to Router.
Any idea how to solve the problem?

Server is 2012 Foundation, domain controller, 10 users, nothing special, just file and database server.

Hi,

Use the MSTSC/ admin  option because this special admin (console login) doesnt require RDP licences.
My guess is there are excisting RDP sessions still open which are not connected to the console.

It may also be an issue with your version of remote desktop. We specified a licensing server for one of our servers and I am no longer able to RDP to it from my Mac but from my Windows machine it works fine.

Try updating to the most recent version of RDP.

Hi,
thanks for your input, but it is not the issue you mention. Cannot access nor with /console nor with /admin switch.

The problem seems is a kind of BUG in 2012, plus Remote Desktop Licencing somehow kicked in. Talking about similar problem here:
http://social.technet.microsoft.com/Forums/windowsserver/en-US/797ab295-aa48-4b73-baa9-4eb7a255ea70/server-2012-refusing-rdp-admin-connection-no-licensing
and here:

The problem escalated to the level, where I need to use:
- TeamViewer access to one of the client machines, which has only USER privileges
- and access to the SERVER via some client machine, and mess with Registry on server

Ouch, glad i didnt touch 2012 yet, i will always stay 2 service packs behind.
So if you havent got licencing servers installed i would say a simple reboot would help or am i over confident with my MS friends product?

Actually, Patrick, I must apologize - I was trying with mstsc /console instead of /admin. Managed to get thru with spare Admin account & mstsc /admin parameter :)

This part solved...now I need to figure out, what the heck happened there.

BTW...When I first saw Server 2012, I felt an urge to kick somebody's ass...and must say that even after some great enhancements in IIS and maybe elsewhere, I still consider it the successor of famous Windows Me :(
