I have not seen your original message. Just wondering what it was and if this problem had anything to do with MS DEP (Data Execution Prevention) ? SP1 turns it on and we have had problems with it killing outlook and ie (citrix says r03/04 fix it but no luck there) _____ From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Joe Howsmon Sent: January 25, 2006 9:42 AM To: thin@xxxxxxxxxxxxx Subject: [THIN] IE and OUTLOOK not opening: Recently I attached a message I was getting involving IE and Outlook 2003 not opening whenever I installed Citrix. I was running Windows 2003 SP1 with Metaframe XPe. IE and Outlook were running fine in Windows mode as well as RDP mode, but when I applied Citrix I was receiving I was unable to open up IE and Outlook through an ICA session. After re-building the server 3 times I was about ready to pull my hair out. This morning I finally found the registry hack to fix this issue. I thought I might share it with the forum in case someone else is currently having or may have the same issue in the future. I deleted the iexplore.exe and the outlook.exe keys using the following path in the registry. HKLM\Software\Citrix\CtxHook\AppInit_DLLS\speedscreen\iexplore.exe HKLM\Software\Citrix\CtxHook\AppInit_DLLS\speedscreen\outlook.exe Joe Howsmon Chief Operation's Officer Howsmon Distributing Company, Inc. 526 South Virginia Avenue Joplin, MO 64801 417-626-1599 Phone 417-626-1544 Fax <http://www.howsmons.com/>
