To deploy this fix across your domain, you will need to use Group Policy Preferences to push the registry modifications to all your Windows 11 client machines. Log into your primary domain controller or any workstation configured with the Remote Server Administration Tools, and open the Group Policy Management Console. Expand your forest and domain structure, then right-click on the specific Organizational Unit that houses your Windows 11 computers. Select the option to create a new GPO in this domain and link it here, giving it a clear, descriptive name so your IT team can easily identify its purpose in the future.
Once the new policy object is created, right-click it and select edit to open the Group Policy Management Editor. You will need to build the path to the registry settings by navigating through Computer Configuration, then Preferences, followed by Windows Settings, and finally selecting Registry. Right-click inside the empty workspace pane on the right side, select New, and then Registry Item. You must perform this action twice to create the two individual registry keys we discussed previously.
For both new registry items, ensure the action is set to Update and the hive is set to HKEY_LOCAL_MACHINE. The key path for both will be SOFTWARE\Policies\Microsoft\Windows NT\Printers\RPC. On your first item, enter RpcUseNamedPipeProtocol as the value name, select REG_DWORD as the value type, and input 1 for the value data. On your second item, enter RpcProtocols for the value name, select REG_DWORD again, and input 7 for the value data. Once you save and close the editor, these settings will push out to your clients during their next background refresh cycle, or your users can trigger it instantly by typing gpupdate /force into their command prompt.
