SCCM – PXE-T04 ILLEGAL OPERATION ERROR RRS feed

  • Question

  • Hi guys

    when machines boot from network i get the following error

    PXE-T04:  Illegal operation error.
    PXE-E36:  Error received from TFTP server

    after searching i found the following solutions but with no luck

    1. DHCP options 66 and 67 configured 
    2. iphelper configured to point to SCCM Server
    3. create a new DWORD value named MaximumBlockSize and set it to 1500 and change it to 1280
    4. set the registry key HKLM\System\CurrentControlSet\services\WDSServer\Providers\BINLSVC\netbootAnswerRequests to true

    any suggestion 

    thanks in advance
