Our small Citrix setup looks something like this:
Server (1 in 1 farm)
" Citrix Presentation Server 4.5 Advanced Edition
" Windows Server 2K3, Standard Edition SP1
Citrix Authentication Method = Explicit
" Web Client XP: Access Client for Citrix, Version 10.00.52110
" Web Client Vista: Citrix XenApp Web Plugin, Version 188.8.131.5257
" Workstation OS: Windows XP SP2 and SP3 (39), Vista (1)
Windows DC, and use Active Directory
Four users have reported seeing a message box with Your password will expire in xx days. Do you want to change it now? Box has Yes and No buttons. Pressing yes, causes a Windows Server 2003 login box to appear with three fields: old password, new password, and password confirm. Cancelling the whole procedure at any time still allows the Citrix user to complete his login and bring up the desired application.
Citrix knowledgebase (CTX112152) refers to this problem, but the solution they are proposing is a Hotfix to XP SP2. Only one of the affected clients has that configuration. One is running on XP SP3, and the other is running on Vista. Im no expert, but patching a Vista machine with an XP SP2 hotfix didnt seem like a good idea.
Since this doesnt affect the other 36 users, I could assume this involves the Citrix user profiles, but I have no clue as to how to begin to debug that. Any ideas on how to debug and correct this (stop login interruption) would be greatly appreciated.
