Fix: Printer Error 0x00000bc4 or 0x00000709 in Windows 11 22H2

 

After updating Windows 11 to version 22H2, your network printers may stop working. Also, the error code 0x00000bc4 (Desc: ERROR_PRINTER_NOT_FOUND) or 0x00000709 (Desc: ERROR_INVALID_PRINTER_NAME) appears when adding a new network printer.

Operation could not be completed (error 0x00000bc4).

 

No Printers Were Found.

The printer name is invalid.

 

Cause

Windows 11 version 22H2 introduced a new group policy named “Configure RPC Connection settings.” This policy setting controls which protocol and protocol settings to use for outgoing RPC connections to a remote print spooler.

The default setting in 22H2 blocks Windows from finding your network printers. This causes your existing printers to be erased, and adding them manually causes the error 0x00000bc4.

Setting “Configure RPC Connection settings” to “RPC over named pipes” fixes the issue.

Solution

To fix the network printer error 0x00000bc4, try these steps:

 

1.    Launch the Local Group Policy Editor (gpedit.msc)

2.    Go to the following section:

Administrative Templates → Printers → Configure RPC connection settings

3.     Select “RPC over named pipes” from the dropdown, and click OK.

4.     Exit the Group Policy Editor.

Registry Setting for the above GPO

[HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Windows NT\Printers\RPC]

There are 2 values that can be configured:

RpcUseNamedPipeProtocol REG_DWORD

0: RpcOverTcp (default)
1: RpcOverNamedPipes

Credits

Printer issue finally resolved. A brand new printer policy in Win11 22H2 is the culprint. "RPC Connection settings. Need to change over to Named Pipes and it works again.#msintune #Memcm pic.twitter.com/7xPS7Xxs0o

Ordinary PC LAN cards and server PC LAN cards differ in several key aspects:

 Ordinary PC LAN cards and server PC LAN cards differ in several key aspects:

1. Performance:

    - Server LAN cards: High-speed, high-throughput, and low-latency (e.g., 10GbE, 25GbE, 40GbE)

    - Ordinary PC LAN cards: Standard speeds (e.g., 1GbE, 100Mbps)

2. Reliability and Durability:

    - Server LAN cards: Built with high-quality components, robust design, and redundant features for continuous operation

    - Ordinary PC LAN cards: Standard components, less robust design

3. Scalability:

    - Server LAN cards: Support multiple ports, teaming, and bonding for increased bandwidth and redundancy

    - Ordinary PC LAN cards: Typically single-port, limited scalability

4. Management and Security:

    - Server LAN cards: Advanced management features, VLAN support, and enhanced security options

    - Ordinary PC LAN cards: Basic management, limited security features

5. Compatibility:

    - Server LAN cards: Designed for server operating systems, compatible with various server hardware

    - Ordinary PC LAN cards: Designed for desktop operating systems, compatible with standard PC hardware

6. Power Management:

    - Server LAN cards: Support wake-on-LAN, remote management, and power-saving features

    - Ordinary PC LAN cards: Limited power management capabilities

7. Operating Temperature:

    - Server LAN cards: Designed for high-temperature environments (e.g., data centers)

    - Ordinary PC LAN cards: Standard temperature range

8. Certification and Compliance:

    - Server LAN cards: Meet strict industry standards (e.g., IEEE, PCI-SIG)

    - Ordinary PC LAN cards: Meet basic industry standards

9. Warranty and Support:

    - Server LAN cards: Extended warranty, dedicated support, and maintenance options

    - Ordinary PC LAN cards: Standard warranty, limited support

Server LAN cards prioritize performance, reliability, and scalability, making them suitable for demanding server environments. Ordinary PC LAN cards cater to standard desktop needs, focusing on basic connectivity and affordability.
