Is it working in terminal services environment?
I have one windows server and 5 users which launch ie. app.exe through RDP protocol (Jestro Cocpit Client - similar to Citrix Client)
When I check server's task manager I see 5 instances of app.exe. But I have one application I would like not to run more than once. I wrote procedure to check unique instances but it doesn't work. It doesn't see other processes, only from my session.
