Windows 2012 R2 Terminal Service does not render Desktop if resolution width less than 600

Recently I had to realize that w2k12 only shows an empty background when connecting to a new Terminal Service session and the requested resolution is 240×320, 480×640 or 480×800. These reolutions are used by Remote Desktop Mobille if you select the option “Fit remote desktop to screen”.

After login, the Start screen (Metro-Ui) is shown, regardless of having set TS to start new sessions always in Desktop mode. If you then start a desktop application or simply the “Control Panel” or “My Computer”, which are Desktop apps both, the screen changes to show an empty (Start screen) background only.


The apps are started on the desktop, but the desktop will not be shown by TS!

rdesktopce builds done with LOW_RES ‘marker’

I have added two new build variants to rdesktopce_rdp5 (see also older article).

Windows Mobile: Hidden Remote Desktop Client Clipboard support

Recently I looked for support of starting an alternative shell when using Remote Desktop Mobile on a Windows Embedded Handheld 6.5.3 device.

MSDN says that I can to specify AlternateShell in a rdp file. As Windows Mobile devices always use \Windows\default.rdp, I added the following two lines and tested what happens.

WorkingDir:s:C:\Program Files (x86)
AlternateShell:s:C:\Program Files (x86)\notepad.exe

Unfortunately the above entries are ignored 🙁

But why? I decided to look inside wpctsc.exe I dumped of a WEH device to see which strings (used sysinternals strings app) are known to the Mobile Remote Desktop client. And, no surprise, AlternateShell is not known inside wpctsc.exe. But I saw two other interesting strings around the ones used in rdp files.

Mobile Development: rdesktop-ce is now Win2008 R2 compatible

Just a short note: rdesktop-ce is now RDP5 capable and can connect to Win2008 R2 Terminal Services.

With the help of bradh I now have a Windows CE fork of rdesktop that does not show modulo 0x108 error any more when run against windows 2008 R2 server.
