When bad printers show up, print-over-RDP doesn't work, and GPO is clear

article #1459, updated 9 days ago

If group policy cache is clear, group policy bugs are ironed out, and you still see bad/nonfunctional printers forcibly recreated and/or print-over-RDP doesn’t work, try this (you’ll need psexec) in administrative CMD:

psexec.exe -s reg delete "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Print\Providers\Client Side Rendering Print Provider" /f
psexec.exe -s reg delete "HKLM\SYSTEM\CurrentControlSet\Enum\SWD\PRINTENUM" /f
psexec.exe -s reg add "HKLM\SYSTEM\CurrentControlSet\Enum\SWD\PRINTENUM"
psexec.exe -s reg delete "HKLM\SYSTEM\CurrentControlSet\Control\DeviceClasses\{0ecef634-6ef0-472a-8085-5ad023ecbccd}" /f
psexec.exe -s reg add "HKLM\SYSTEM\CurrentControlSet\Control\DeviceClasses\{0ecef634-6ef0-472a-8085-5ad023ecbccd}"

Any SMB-mapped printers will be deleted or grayed, IP direct printers will remain.
