When aclient tries to connect to the Terminal Server (TS), and error message is returnedasking for the user to lower their resolution.
The totalresolution for all monitors combined is higher than 4096x2048 (height or width are over the limit).
Affected systems are: XP/Vista/Win2003/Win2008.
Resolution can be higher on: Windows7/Win2008R2 systems. This is a requirement for both client and server parts.
No solution, as this is an MS limitation as imposed by Microsoft Remote Desktop Protocol (RDP) which is described in the Microsoft Article linked below:
As a possible workaround the user can access client option (whether using AppPortal or Web-IT) and lower the resolution to a smaller value.
NOTE: Client will lose spanning option when not running in full screen mode.
