I am trialing a vnc manager I run a windows 2003 Server headless server, and use it to control other machines using RDP and VNC. To access the server itself I use RDP so seems perfect to for vncmanager, unfortunately the rdp screen size option in vncmanager wont let me change it only has one entry which is always the same as the resolution of the RDP connection to the Server itself, ie if I connect to the Server at 1280 X 1024 it forces me to use 1280 X 1024 to connect from it to all other rdp connections making me use full screen for all of them. Is this by design or is it a bug, this does not happen on the standard vanilla windows RDP client or the remote desktops management console. I have tried both 2.5x and 3.0 and they both exhibit the same problem.

Lucian,
this is not a bug. And I probably can explain why you are getting different results with the VNC Manager and native client.

In the VNC Manager the RDP connection properties screen has a combobox with resolutions. The list of the values presented in the combobox is the list of screen resolutions supported by the graphics card. And when you login to a remote computer via RDP, the Terminal Server installs a special graphics driver and reports only one resolution - the screen size of your RDP client. You can confirm it by opening the Display properties of a desktop you are viewing via RDP session. That's why you are getting the behavior you described.

On the other hand, native RDP viewer doesn't enumerate current screen resolutions supported by a graphics card and has that list hard-coded.

We are probably will move to the "hard-coded list" scheme too some time after next week to be released v3.0 release.

I'm going to disagree and say this is a bug. When I use the built-in Remote Desktop client from Microsoft, I have a choice for the resolution that I connect to a remote system with.

I am currently trying out VNC manager and this is currently a 'deal breaker' for me. If I can't designate the resolution for the system I'm trying to RDC to, the software is pretty useless to me. I understand that VNC comes uses the resolution on the remote system, but RDC doesn't have this limitation.

Please let me know how to work around this.

Thanks,

Please let me know how to work around this.

Eric, this design flaw (I still tend not to call it a bug, since this RDP resolution behavior works the way we wanted to implement it) is going to be fixed in the v3.1 release, which should be released with-in 1.5-2 months time frame.
