    After installing KB5009545, IP Security (IPSEC) connections which contain a Vendor ID might fail. VPN connections using Layer 2 Tunneling Protocol (L2TP) or IP security Internet Key Exchange (IPSEC IKE) might also be affected.

    Workaround: To mitigate the issue for some VPNs, you can disable Vendor ID within the server-side settings. Note: Not all VPN servers have the option to disable Vendor ID from being used.

    Next steps: We are presently investigating and will provide an update in an upcoming release.

    After installation of KB5006667, Windows print clients might encounter the following errors when connecting to a remote printer shared on a Windows print server:
    • 0x000006e4 (RPC_S_CANNOT_SUPPORT)
    • 0x0000007c (ERROR_INVALID_LEVEL)
    • 0x00000709 (ERROR_INVALID_PRINTER_NAME)
    Note: The printer connection issues described in this issue are specific to print servers and are not commonly observed in devices designed for home use. Printing environments affected by this issue are more commonly found in enterprises and organizations.
     
    Workaround: You can take steps to workaround this issue on print servers that meet the following prerequisite:
     
    • Print clients must have installed a Windows update released on or after January 2021 before the print server has installed KB5006667.
    Ensure that network security and VPN solutions allow print clients to establish RPC over TCP connections to print server over the following port range:
    • Default start port: 49152
    • Default end port: 65535
    • Port Range: 16384 ports
    Please refer to these articles for further guidance:
    You also benefit from using client side rendering for print jobs. The 'Render print jobs on client computers' option is available from the printer's device Properties, and it is recommended that its checkbox is selected on the print server. Note this step will not help if clients have overwrites which prevent the server setting from taking effect.
