During a final checkup into one of ours Windows 2008 R2 server, I noted groups of 3, 4 events 1111 into Event Log.
All are TerminalServices warnings about several needed printer drivers not found, like the following:
Driver Send to Microsoft OneNote 16 Driver required for printer Send To OneNote 2016 is unknown. Contact the administrator to install the driver before you log in again.
After some further investigations, I discovered that they are about Remote Desktop connections, when the server tried to replicate the same client printer drivers.
The solution in this case is quite simple:
- start Remote Desktop Session Host Configuration under Administrative Tools -> Remote Desktop Services
- right click RDP-Tcp into Connections pool, and click Properties.
- check Windows Printer into Client Settings
After that your server will stop to try to install/map RDP client local printers.
