Windows 2012 - RDP error

Remote users trying to connect to server get the following error:-

Remote Desktop can't connect to the remote computer for one of these reasons:-
1) Remote access to the server is not enabled
2) The remote computer is turned off
3) The remote computer is not available on the network


Not (1) - I can connect locally
Not (2) - same reason

Where to start looking?



Hi,

When you say you can connect locally, do you mean directly to the console of the server, or from a remote session in the office where you are sitting?

If you have made sure that you have remote access enabled (setting > server info > advanced system settings > remote tab > "allow remote connection to this server" is ticked.

Then check that the users can ping the servername or IP from wherever they are trying to connect from.

Are you using a VPN for the remote users, or should they be able to connect without from anywhere?



Can connect using RDP from local office.

Unfortunately, pretty sure firewall will block ping.

Remote users use vpn.



If you are using VPN, the firewall should not block the ping as it would essentially be an internal connection.

Unless the server is in a DMZ and in that case, you would not be able to ping from your desktop either.

If the VPN is an isolated VLAN, you need to look at your DNS settings on that VLAN and make sure the users can resolve the servername in the case they cannot ping it...

Also you could try telnet over the VPN on port 3389 (RDP) to ensure you can connect to the server .



Ah it seems one server on the subnet works ok (Call is ServerA) (both servers are 2012) but another one (call it ServerB) does not.

Also, user can RDP to ServerA and then RDP from there to ServerB no problem.

BTW - how do you access the remote setting? Looking at the server roles on the working one the Remote Access role is not even installed? Confused.
