Error 7025 shadow failed. An attempt has been made to connect to a session whose video mode is not supported by the current client.
When using the shadow taskbar, the shadower received the following error messaged:
Shadow failed. Error code 7025 (Error 7025 An attempt has been made to connect to a session whose video mode is not supported by the current client.) The shadowers session was configured at a lower video or color depth than the shadowees.
From the Citrix Management Console, choose the sessions for the shadower and shadowee, and double-click the session Information tab. Verify the shadowers video and color depth is greater than the shadowees. To do this, from Citrix Server Administration (Mfadmin.exe), highlight the session in the left-hand pane beneath the server and view the Information tab in the right-hand-pane. It is important to note that it is the capabilities of the client and not the current session that is the determining factor.
For example, you may have true bit color set on the local desktop but the session may be configured for 256 colors. This could also be true with HRES and VRES settings. If the session is 800×600 but the client desktop is set at 1024×768 and the shadower shadows a 1024×768 session, the shadowed session can use scroll bars to handle this condition. However, if this client tried to shadow a session larger than 1024×768, shadowing would fail because the client desktop would not support a session greater than 1024×768. You may want to use Notepad to review the ICA file created per Troubleshooting and Explaining Citrix ICA Shadowing.
