**Environment:**

- Windows Server 2016 (10.0.14393) — domain BELCHER

- Windows 11 (10.0.26200) — PC04, IP 192.168.0.35

- Printer: Zebra ZDesigner GX430t, shared as ROTULO01

- Printer connected via USB on PC04

**Main error:** `0x00000040 - The specified network name is no longer available`

**What we already tried:**

- Added `RpcAuthnLevelPrivacyEnabled = 0` on both machines

- Added `RpcUseNamedPipeProtocol = 1` on Server 2016

- Added `713073804 = 0` in FeatureManagement\Overrides on both machines

- Enabled SMB1 on Windows 11

- Set `RequireSecuritySignature = 0` and `AllowInsecureGuestAuth = 1` on Server 2016

- Installed Print-Server role on Server 2016

- Tried via IP, hostname, PowerShell `Add-Printer -ConnectionName`, and `rundll32 printui.dll`

- Opened firewall ports 135, 139, 445 on Windows 11

- Changed Windows 11 network profile to Private

- Disabled password-protected sharing on Windows 11

- Installed ZDesigner GX430t driver on Server 2016

- Rebooted both machines multiple times

- SMB log showed Server 2016 was trying SMB1 — enabled SMB1 and error briefly changed to `0x00000709`, then returned to original error

**Goal:** Install the shared printer on Server 2016 because a legacy software (Fórmula Certa) does not print via direct TCP/IP port — only works with a Windows shared printer.
