We have a number of new hand-held terminals running Windows CE. These are used to connect to a Windows Server 2012 R2 by Remote Desktop.
The problem is that there is a long delay (up to 30 seconds) while the client displays "Connecting...". Once connected though, it works fine.
The terminals have no Internet access, and IP addresses assigned by a local router. The RDP connection uses the IP address of the server.
If using Windows computer, the session connects immediately, so we think it is a compatibility issue with the terminals. Oddly though, we have the same model of terminal at other sites, also connecting to Server 2012 R2 - and these have no problem.
What settings must we change to avoid this delay connecting?
