Can't connect to the remote computer, remote desktop 2008 r2

Question

Before all, sorry by my english.

Well thats the situation, i have installed a Windows Server 2008 R2 with Remote Desktop services for accessing outside. What it's happening is that when i try to stablish connection from client computer, every things appears to go fine, except that if i have not open a local session with the same user, i get the error "Remote Desktop can't connect to the remote computer..."... but if i had previously open session with that user locally on server, the remote conection is opened perfectly...

Any idea???

Solution

Did you go through the steps necessary to enable remote desktop on the windows 2008R2 system? I'd follow the directions here: http://technet.microsoft.com/en-us/library/cc794832(v=ws.10).aspx

accounts and group memberships at Local and Domain Default Groups (http://go.microsoft.com/fwlink/?LinkId=83477).

excerpt from the above URL:

To enable Remote Desktop locally by using Server Manager Open Server Manager.

To open Server Manager, click Start, point to Administrative Tools, and then click Server Manager.

In Computer Information, click Configure Remote Desktop.

In the System Properties dialog box, under Remote Desktop, click one of the following options:

Allow connections from computers running any version of Remote Desktop (less secure). Use this option if you do not know the version of Remote Desktop Connection that will be used to connect to this server.

Allow connections only from computers running Remote Desktop with Network Level Authentication (more secure). Use this option if you know that the users who will connect to this server are running Windows Vista or Windows Server 2008.

Review the information in the Remote Desktop dialog box, and then click OK twice.

Yes. I have included the right users and/or groups into the "Remote Desktop Users". I have included the group "Remote Desktop Users" into the policy "allow start session through remote desktop services".

I have the same configuration in another server and works perfectly, but in this one, i dont know why exactly i'm having this issue. The most rare thing is what i explained before, trying to establish a remote desktop session with aministrator user, for example, if i had a local session opened with that user (Admin), i can open remote desktop session with no problems, the local session is finished and the remote one is opened without probles, but if i have no sessions opened in the server locally, i get the error... why???????

Firewall rule open to allow RDP traffic in? This would be the firewall on the 2008R2 box.

Firewall is disabled :(
