  • Hi All.

    I've configured a WDS server on Server 2008 R2. I've set the response policy to respond to all, I've configured DHCP correctly but when I do a PXE boot from some clients PC `s get the Following error, others works fine.

    PXE-T04: Access Violation
    PXE-E36: Error received from TFTP server
    PXE-M0F: Exiting PXE ROM

    Machines with trouble are HP branded PC`s

  • Hi Gvintik,

    does the tftp server itself work correctly?

    f.e is it possible to transmit/receive a file from a tftp client to/from server?

    Perhaps there is a firewall enabled between clients and server that could block the necessary data traffic?

    Best regards

  • Hi,


    Access Violation could be caused by DHCP. You may need to configure IP Helper setting on the router or configure DHCP scope options as appropriate. Here I would like to share the following similar issues:

    Best Regards

  • Please i need help i am a newbie at this just trying my hands on learning stuff on  my won. i configured WDS and Microsoft DHCP on Windows 2008 r2. I also have a separate laptop running virtual box where i have installed windows 7 hp and i want to capture the image on the WDS server. Every time i try a PXE boot on the win 7 image on virtual box i get an error saying "TFTP error 4 Access violation". All the solutions i have seen are referring to using Linux DHCP servers but my DHCP server is running on the same machine as WDS . So its a Microsoft DHCP server.

    I am thinking there is something wrong with my configuration for WDS please help anybody?

    My virtual box settings i have the network settings configured as bridged adapter.

    unfortunately like i said the solutions i have seen refer to the same problem but the scenario in those cases show the use of an external DHCP server such as a Linux box or Cisco. In my own case i am using the DHCP server on my Windows 2008 r2 so i dont think i need to configure IP Helper.

    Another thing i tried was doing a TFTP from command line to the WDS server and i got the same error message i got during the pxe boot. See below errors i got during pxe boot from virtual box and the error i got when i tried tftp from command line in windows.

  • Old thread but first hit on Google when searching for "PXE-T04: Access Violation", so let me tell you how I fixed this.

    My WDS environment used to work alright. After uploading a new image I received the error "PXE-T04: Access Violation" when booting with PXE.
    It had nothing to do with my DHCP server which was configured right and hasn't been changed for a long time.

    I ended up  removing the WDS server role. Don't panic, all your images will be preserved. After rebooting the WDS server I installed the WDS server role and pointed to my "old" images folder. Just configured the WDS server from the WDS console and everything is back to normal.

    Good luck everybody,
