Windows 10

 Windows 10 Printer sharing 






❌ Operation failed with error 0x0000011b

is a known Windows update security issue that started appearing around late 2021 when Microsoft disabled remote printing over SMB by default to fix a security vulnerability (PrintNightmare).



Permanent Fix for Error 0x0000011b (April 2025 working method)

You need to add a registry key on the printer host PC (192.168.0.100) to disable RPC encryption enforcement:

🔧 Step 1: Add Registry Entry on Host PC

Save this as fix_0x0000011b.reg on 192.168.0.100 (printer host):

reg

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print]
"RpcAuthnLevelPrivacyEnabled"=dword:00000000

  1. Save as .reg file

  2. Right-click > Merge

  3. Restart the PC

✅ Or Run this Command in CMD (on Host PC)

cmd

reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print" /v RpcAuthnLevelPrivacyEnabled /t REG_DWORD /d 0 /f

Then reboot.

🔧 Optional: Full Batch Script to Fix 0x0000011b on Host

bat

@echo off
echo Disabling RpcAuthnLevelPrivacyEnabled to fix printer error 0x0000011b...
reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print" /v RpcAuthnLevelPrivacyEnabled /t REG_DWORD /d 0 /f
echo Done. Please restart this PC for changes to take effect.
pause

🔄 Step 2: Restart Host & Client PCs

  • Restart the host PC (192.168.0.100) after adding the registry

  • Restart the client PC

  • Now try to connect the printer again
