Hi, I am on a x200 Thinkpad (Core2 Duo) with Windows 7 x64 Ultimate SP1 with 4GB of RAM. I have applied the the Concurrent RDP sessions patch that is published here at techspot and the one from expert windows forums (I am not yet allowed to post links) The issue I have with this is that I can log on to my computer with concurrent sessions but when I do, the memory usage jumps up to 100%. Before the second session was started it was around 50 %. This results in ressource related error messages when starting programs. Unfortunately, I cannot see which program is causing this, not even in task manager (as admin), Ressource Monitor, or Process Explorer. The system is running the follwoing software on start up - Bitvise SSH Server - Symantec Endpoint Protection (changed to that coming from AVG) - Teamviewer - VirtualCloneDrive - Squeezebox Server (Logitech Media Server) - Sabnzbd as service - Dataram RAMdisk Anyone with similar issues or even a solution? Thanks guys!
