Windows 2012 and Remote Desktop Connection

Hello everyone,

I am sure some of you came across with the issue I currently have with Windows 2012.

Strange things do happen when I try to connect from my desktop (Win 7 Pro 64-bit) to  Win 2012

1. From cmd line I run  mstsc /admin, the client is open, specify the IP of Windows 2012, I can connect, no problem

If I don't use  /admin the connection fails with the following message:

This computer can't connect to the remote computer.  Try connecting again. If the problem continues, contact the owner of the remote computer or your network administrator

Well, I checked and db-checked the settings, all appears to be correct.  There are differences between 2008 and 2012  however I am not sure  what causes this RDP connection to fail

Any idea what might cause this ?  

Thank you in advance for your reply

Cheers

Have you checked which option is chosen on this server for the RDP sessions, as in what is shown in the article here:

It sounds like maybe you've got options chosen that are restricting who can connect and how, so this is a place to start.

Thanks jecgomrec for your extensive answer .  I just tried and, unless I use  /admin, I cannot connect , either using a local account or an AD account

Few examples :  

my  firstname.lastname  AD account is member of Domain Admins, so, by default, I have RDP login priviledges to the server,  I cannot use it unless I have specified   /admin

Administrator (this time the local account)  cannot be used unless /admin is specified

DomainName/Administrator  (AD Administrator)  same issue,  /admin must be specified

Tried to logon from a different PC,  exactly the same issue

Cheers

I think the first part will help you understand and find your problem.
It was a Windows 2012 firewall issue ,  thanks !
