Thanks to everyone who responded. I have not had a chance to test further...but I plan to later in the week. Yes I can recreate the issue when logged on as Administrator through a RDP / ICA session.

The first comment is that it's unlikely you'll get any useful support from Timberline. It's also unlikely that XP FR3/SP4 would have caused the problem, whereas the original Win2k Post SP4 rollup caused havoc in some instances. There are a couple of things you can try that might point you in the right direction. Can you reproduce the problem as an administrator? If you can, put your session in "install" mode (change user /install), run up Timberline and see if the problemit still happens when you exit. regards, Rick Ulrich Mack Volante Systems ________________________________ From: thin-bounce@xxxxxxxxxxxxx on behalf of Matthew Shrewsbury Sent: Sat 24/09/2005 5:30 AM To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: Application Error Anyone have any ideas on this? Matthew Shrewsbury, MCSE+Internet MCSE 2000 CCA Server+ Senior Network Administrator -----Original Message----- From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Matthew Shrewsbury Sent: Thursday, September 22, 2005 3:27 PM To: thin@xxxxxxxxxxxxx Subject: [THIN] Application Error I have an application called Timberline installed on Windows 2000 SP4, Citrix XPA FR3 SP4. Around the time I upgraded to Citrix SP4, Win2K Post SP4 patch, and upgraded to the latest version of Timberline I started receiving an error when Timberline is closed. I didn't detect any errors because no one reported the problem for sometime so I kept upgrading and service packing until everything was updated. After a week or two users reported that when closing out of some Timberline screens or closing out of Timberline they would receive an error: "The Instructions at 0x00ba0b60 referenced memory at 0x00ba0b60. The memory could not be read". You click ok on the error message and it does not appear to cause any problems. 1- I investigated and found that the error only occurs in an ICA or RDP session only. From the console on the server it does not error. 2- I've tried regmon and filemon and neither show any problems that I can tell. 3- I've tried almost everything the vendor has suggested, although they seem to have no clue. They have had me try different printers and are now telling me to reinstall TCP/IP. 4- All other applications (Office, IE, Acrobat) are working perfect on the same servers. I don't know if this is being caused by a service pack, hotfix, application update, or corruption has caused this. I have two servers load balanced and they both exhibit the same symptoms so I think corruption is not likely. Any ideas how I can troubleshoot this? It does appear to be terminal services related as it only occurs within ICA or RDP sessions. Thank you!
