I am working with a client's system to migrate from 2003 terminal server and domain controller to 2012 r2.
Terminal Server running 2003 R2.
All shared data and database software was on the SBS server and remote users would login to the terminal server and access their files, it's pretty well locked down.
DataServer - 2012 R2 Standard
RDP Server - 2012 R2 Standard
Migrated AD, DNS & DHCP. Migrated shared folders and databases to DataServer. Installed RDP Services using Quick settings. Users can login to remote desktop server without issues.
Problem: I logged in as a few users and manually mapped drive S to a shared folder on DataServer using the GUI and check the box to reconnect. Once I log off and log back in, the mapping is no longer there. IF the user is a domain admin, then it remembers! I also tried creating a GPO to apply just that one drive mapping, it says it runs and then gives me an error in the even log: "failed with error code '0x80070035 The network path was not found'. I get the same sort of error trying to use 'net use' from a command prompt. I wound up moving the folder back to the old server and the manually mapped drive works just fine.
I'm thinking there is either a security setting or a user setting somewhere leftover from the old terminal server settings. Should I just remove all those GPO items that don't apply anymore to the new system? Also, I'm at a loss for a place to apply detailed user settings to the users who are going into remote desktop.
