How to Install TFTP Server on Windows Server 2012 R2 All Windows Server version support the ability to run built-in TFTP server. Though there is no dedicated role or service of the TFTP server (don’t look for it in the FTP section of your IIS server ), this feature, like in Windows Server 2003, is a part of Windows Deployments Services (WDS). The ftpcconnect function starts the FTP client on the TCPnet system. This causes the FTP client to then start a FTP session by connecting to a FTP server on the TCP port specified in the function argument. If the port is not specified, that is the argument port has a value of 0, the system uses a standard FTP server port to connect to. The argument ipadr points to an array of 4 bytes.

When I boot my host from pxe server, pxe client download shim from tftp server successful, but shim failed to fetch netimage with error message like: Unable to fetch tftp image: TFTP Error, start_image returned tftp error |

Per UEFI SPEC, EFI_TFTP_ERROR from EFI_PXE_BASE_CODE_PROTOCOL.Mtftp() means 'A TFTP error packet was received during the MTFTP session'. Unfortunately, shim currently won't show the details of TFTP error code. According to RFC1350, the possible error codes are: 0 Not defined, see error message (if any). Maybe we can fetch the error code after getting EFI_TFTP_ERROR to help the user to identify the issue. |

I have been having issues for a while trying to get this to work, I may have an idea of your issue. The shim REQUIRES your DHCP server to be giving out 'next-server' pointing to your TFTP host, if you are running proxyDHCP and dont have your primary server giving out a next-server address it will fail this way. |
I've finally solved the problem preventing me from updating my Dell Inspiron 7537 laptop from Windows 8.1 Home to Windows 10 as described in https://www.tenforums.com/installatio...at-next-2.html.
The installation was consistently failing at the point where Windows is about to restart for the first time with a grey information window titled 'Something has happened' with the information 'Windows 10 installation has failed'.
I've posted below how to diagnose and repair your PC to enable the Windows 10 installation to proceed. The installation should proceed smoothly once the error is corrected.
Symptoms
- You are booting in UEFI mode i.e. you have a separate EFI System Partition (ESP) on your system disk.
- You are updating from Windows 8.1 to Windows 10 using the USB install disk, a mounted ISO update image or Windows Update.
- The installation consistently fails at the point where Windows is about to restart for the first time with a grey information window titled 'Something has happened' with the information 'Windows 10 installation has failed'.
- The setuperr.log installation error logging file contains error 0x80004005 towards the end of the file and there is an error message referring to 'Failed to backup BCD database'.
- The command bcdedit /export <yourfilename> fails with the error 'The store export operation has failed. The handle is invalid'.
Diagnosis
- The ESP partition has become corrupted causing the failure to export the boot configuration data and failure of the Windows 10 installer. Note your PC may boot to Windows 8.1 normally despite the corruption.
- The boot configuration data on the ESP partition needs to be repaired to enable the installation to proceed.
Solution
The successful solution I implemented is shown below.
- Perform a full backup of your Windows system (I recommend Macrium Reflect). Your PC may be unbootable if the repair is not implemented correctly.
- Boot the computer using the Windows 8 installation bootable DVD. Make sure you boot the media in the same configuration as your UEFI installation.
- On the ‘Windows Setup’ wizard click on ‘Next’ and click on ‘Repair your computer’.
- You will then see a blue screen and an option to choose.
- Click on ‘Troubleshoot’ then click on ‘Advanced Option’ and then click on ‘Command Prompt’.
- Type these commands on the Command Prompt for UEFI configuration:
- diskpart (opens Disk Partitioning tool)
- select disk 0 (or whichever disk is your system disk)
- list volume (please note the number of the volume that has no drive letter assigned and has FAT32 listed in the FS column, usually the only FAT32 volume/partition)
- select volume x <where x is the number of 100-500 MB FAT32 volume with no drive letter, or with label ESP, EFI or SYSTEM>
- assign letter=Z: (gives drive letter Z: to EFI System Partition)
- list volume (to check drive letter Z: is correctly assigned)
- exit (closes Disk Partitioning tool)
- cd /d Z:EFIMicrosoftBoot (changes current folder in Command Prompt window)
- attrib Z:EFIMicrosoftBootBCD -h -r -s (removes hidden, read-only and system attributes from BCD folder)
- bootrec /fixboot (writes a new boot sector to the system partition)
- ren Z:EFIMicrosoftBootBCD BCD.old (renames BCD folder to BCD.old)
- bcdboot c:Windows /l en-gb /s z: /f ALL (en-gb is for the UK - use your own locale)
Installation Checking
Your boot configuration is probably correctly configured if the following commands report correctly.
- Confirm the PC boots
- Run bcdedit and confirm boot configuration is correct. You can use bcdedit /enum all for the full details,
- Run reagentc /info and check recovery configuration is correct. In my case, Windows RE was not configured and I had to run regaentc /enable to enable it.
- Run bcdedit /export <yourfilename> and confirm the command works
- Minitool Partition Wizard may be used to explore the EFI system partition and confirm the correct files have been copied
Your Windows 10 installation should proceed correctly once the above error is fixed. I only wish Microsoft would use more informative error messages which would have saved me significant time and effort trying to solve this problem.
