The background bitmap behind the windows logon screen appears tiled.

By default the Ica256.bmp file, located in C:\Program Files\Citrix\System32, is the bitmap that is displayed in the background of the msgina or nwgina. If that file is renamed, the background image is completely removed. However, if you want to delete the tile effect and just have the bitmap centered behind the logon screen, simply follow the instructions below:
