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 Thanks

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 Thomas Lambertz

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: PXE T04 access violation http://social.technet.microsoft.com/Forums/en/configmgrosd/thread/26af0eb0-08c6-453b-9edf-86ed9ae26ee7 Server 2008 Windows Deployment Services TFTP Error PXE-T04 PXE-E36 http://social.technet.microsoft.com/Forums/en-US/winserversetup/thread/e39e4c8c-ed48-460b-901b-aebf1f1f8d95 Best Regards DalePlease remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.
