Ran into an issue where a Windows 2003 R2 servers login screen was using a black color scheme. You could see part of the Windows 2003 login logo but nothing else. This issue is caused when all color schemes in the computer’s default profile may have been set to black for every scheme element.
To correct it you can export the HKEY_USERS\.DEFAULT\Control Panel\Colors registry key from a working server and import in the system that has the issue. You can also copy the text below and save as .REG and import it into your system.
Windows Registry Editor Version 5.00 [HKEY_USERS\.DEFAULT\Control Panel\Colors] "ActiveBorder"="212 208 200" "ActiveTitle"="10 36 106" "AppWorkSpace"="128 128 128" "Background"="102 111 116" "ButtonAlternateFace"="181 181 181" "ButtonDkShadow"="64 64 64" "ButtonFace"="212 208 200" "ButtonHilight"="255 255 255" "ButtonLight"="212 208 200" "ButtonShadow"="128 128 128" "ButtonText"="0 0 0" "GradientActiveTitle"="166 202 240" "GradientInactiveTitle"="192 192 192" "GrayText"="128 128 128" "Hilight"="10 36 106" "HilightText"="255 255 255" "HotTrackingColor"="0 0 128" "InactiveBorder"="212 208 200" "InactiveTitle"="128 128 128" "InactiveTitleText"="212 208 200" "InfoText"="0 0 0" "InfoWindow"="255 255 225" "Menu"="212 208 200" "MenuText"="0 0 0" "Scrollbar"="212 208 200" "TitleText"="255 255 255" "Window"="255 255 255" "WindowFrame"="0 0 0" "WindowText"="0 0 0"
Log out and reconnect and all will be back to as before
