CTX105583 - Seamless Is Not Working and Color Depth In the Session Is Only 16 Colors Instead of 256 Colors This document was published at: http://support.citrix.com/kb/entry.jspa?externalID=CTX105583 Document ID: CTX105583, Created on: Dec 14, 2004, Updated: Dec 16, 2004 Products: Citrix MetaFrame XP 1.0 for Microsoft Windows 2000, Citrix MetaFrame XP 1.0 for Microsoft Windows 2003, Citrix MetaFrame Presentation Server 3.0 for Microsoft Windows 2000, Citrix MetaFrame Presentation Server 3.0 for Microsoft Windows 2003 Symptoms Any new seamless session on any server in the farm starts into a non-seamless window and has a color resolution of 16 colors instead of the default 256 colors. Session sharing is no longer working. There is no error message. Shift + F2 does not change anything. The same issue occurs with a new application and with a loop back connection. RDP does work. Cause The value under maximum memory to use for each session graphic may have been changed to 0 or 150 (or a value too small, see Help in the Management Console for details about how to determine this) instead of the default value of 5625 KB. This may have been caused by a corruption in the data store. Resolution From the Management Console, open the farm properties and select ICA settings. Modify the maximum memory to use for each session graphic to 5625 KB.(or any value above 150 depending on your user environment)
