We're using Windows Server 2012R2 Standard (6.3.9600) as terminal server. After installing KB50116681 users connected using RDP are not able to print using redirected printers. If users send file to redirected printer they get error message - Handler not valid.
After opening Devices and printers in Control panel and selecting on of redirected printers and selecting Print test page we get error message - Unable to print test page. System doesnt recognize requested command.
After uninstalling this update, everything again works just fine.
Do you have any information regarding this update causing similar problems? What could cause this issue?
