Dont install it id you use thin clients or win2k clients: http://support.citrix.com/isearch!execute.jspa?searchQuery=update+rollup+1&searchType=0 When the users open a desktop or a publish application, the user only have a blue screen and never logon. On the taskmanager, I have a winlogon.exe process that take 25% cpu. Rdp connections have no problem. Citrix have acknowledged the issue, i got this from support - 'Citrix Support has discovered that this rollup is causing an issue with ICA connections. The symptoms being experienced are that you login to ICA Session and you get a blue desktop and nothing else. If you run a utility like Qslice on the server, you will see that Winlogon is pegging the CPU. Do not install this rollup until a resolution is available.' ******************************************************** This Weeks Sponsor: Lakeside Software SysTrack is the easiest to use, most complete way to monitor system and application performance.
