Might check permissions WebDir\Citrix\MetaFrameXP\NFuseIcons This is the folder used to store application icon image files. The web server receives the icon data from the MetaFrame XML service, writes GIF images to disk, and then serves the images over HTTP to the user. If Web Interface is configured for only explicit authentication, the IWAM_MachineName account is responsible for writing the files to disk and the IUSR_MachineName account reads the files during delivery. If Web Interface is configured for Desktop Credentials Pass-Through or Smart Card authentication, IIS impersonates the user account for reading and writing the icons.

I have a Windows 2000 (Domain A) mixed mode domain with a one way trust to a Windows 2003 (Domain B)native mode domain. Users are presented with all applications from the Windows 2000 domain (A) when they log on with pass through authentication but they receive no applications from the Windows 2003 domain (B). If they log on with a explicit logon they receive applications from both farms and life is good. My WI site is set to the xml server in both domains. Thanks in advance and please let me know if I am not being clear. I have posted this message on the Citrix forms but had no reply thus is why I am posting here. (probably should have started here first anyways!)
