Hello, I recently set up a windows 2008 r2 server to replace an older 2003 server with older software. when I login to the server with admin everything works, but when i log in with user accounts under our Active directory they are configured to boot a program on startup. I was getting a message saying unable to find program and then it would log you out of the server. So i figured it was an issue with booting on start so i disabled this is remote desktop session host config. Now when they boot to desktop i cannot see the drive the program is installed on. So i figure this is my problem, those accounts must lack access to the drive/applications. My question is how to set the permissions for these accounts to be able to access the drive/application i need to boot on start up. WE have an active directory server, do i need to install anything on this new server for AD ? Do i make changes in AD ? on the server itself ?
