Its normally an MSLicensing issue - is there anything in the event log on the ctx server? When you say you've deleted the key you have deleted it from the workstation? And made sure they have write access to that component for that key? What happens if (temporarily) you make the user an admin on that machine? _____ From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Rick Fogarty Sent: 04 January 2006 16:21 To: thin@xxxxxxxxxxxxx Subject: [THIN] MF Server login I just inherited a MF Server (version 3.0 Build 2085) that I'm having an issue with for one computer (well two now). When this user logs into the web interface on the MF server, he is prompted for credentials and it processes them. Once he selects the farm, it shows the published apps and desktop. However, when selecting any of the available options, the process hangs with the "preparing to connect" dialog box showing. I found a link on Citrix's web site (http://support.citrix.com/forums/thread.jspa?messageID=258165 <http://support.citrix.com/forums/thread.jspa?messageID=258165&fromSearchPag e=true𿁵> &fromSearchPage=true𿁵) that stated to delete this key: HKEY_LOCAL_MACHINE\Software\Microsoft\MSLicensing\Store\LICENSE00x I've done so, but still am having issues. I've looked at the other suggestions on Citrix's site and nothing appears to work. When this same user logs in using another system, it has not issue. Any suggestions? Thanks! Rick
