Fix Network and Printer Share 0x0000011b error

✅ Save as network-print_fix.reg and then merge it

Windows Registry Editor Version 5.00[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\LanmanWorkstation]
"AllowInsecureGuestAuth"=dword:00000001[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Print]
"RpcAuthnLevelPrivacyEnabled"=dword:00000000

What these actually do

• "AllowInsecureGuestAuth"=1
  → Allows guest (no password) SMB access
  → Needed for some old NAS/printers
• "RpcAuthnLevelPrivacyEnabled"=0
  → Fixes printer error 0x0000011b (relaxes RPC security)
