>Hi,

>I am currently running a Foreclosure Management App in a desktop dbf environment with between 40-50 users. The app is distributed locally, having a copy on the server, and when they sign on the app checks if server has a newer version and then copies the exe to the local PC. It has been working fine for years but some users will be working from home and want access remotely.

My network guy said when more than one session is instantiated on the server (running exe on server), you get an access denied. It seems only one session can run using REMOTE DESKTOP SESSION HOST on the server(Server 2012 R2).

By default Windows Server 2012 R2 allows 2 simultaneous RD sessions. They must be under different accounts or they will step on each other - later logons will force-disconnect earlier ones (last logon wins).

Those default sessions are for administration, not running user apps. If you want to run apps you should have Remote Desktop Services licensed and installed, and it should be on a server computer (physical or virtual) dedicated to that purpose.

You'll have to modify your app so that neither your launcher nor components of your executables try to overwrite files that may be in use by others on the same machine. This means, for example, putting temp files into users' profiles rather than fixed locations such as C:\Temp.
