MDT error 0x80004005 is an unspecified error, not a diagnosis. In a LiteTouch deployment, hexadecimal 0x80004005 is often the final return code after an earlier task-sequence, script, image, network, disk, or firmware operation failed. The reliable fix is to identify that earlier failure in BDD.log, LiteTouch.log, or (when Configuration Manager is involved) smsts.log, then correct the dependency that actually failed.
The decimal form, 2147467259, describes the same value. Do not start by repeatedly rebuilding media or changing random task-sequence settings. Capture the failing step first, then use the matching troubleshooting path below.

What the MDT 0x80004005 error means
Windows classifies 0x80004005 as an “unspecified error.” The number does not identify one root cause, one damaged file, or one universal repair. MDT can surface it when LiteTouch reaches the end of a failed operation and has no more specific code to return.
That is why two deployments can show the same message while requiring completely different fixes. One may have lost network access in WinPE; another may be using an incompatible ADK component; a third may have a bad command line, WIM, partition layout, or firmware-mode mismatch. Treat the code as a wrapper around the first meaningful error in the logs.
#1 Best Overall
The wording often appears as “LiteTouch deployment failed, Return Code = 2147467259 0x80004005.” It is not, by itself, evidence of malware or proof that the operating-system image is corrupt.
Capture the failure before changing anything
- Reproduce the deployment once. Write down the exact task-sequence step displayed immediately before the error. Record whether the failure occurs while booting WinPE, connecting to the deployment share, partitioning a disk, applying the operating system, running a command, or completing a later configuration step.
- Collect the relevant logs. Save
BDD.logandLiteTouch.logfrom the affected deployment. If Configuration Manager is part of the process, also collectsmsts.log. Export or copy the deployment summary for the phase that failed. - Open the logs in CMTrace. Microsoft recommends CMTrace because it makes timestamps, severity, and interleaved entries easier to read than a basic text editor. Keep the original files unchanged and work from copies when possible.
- Read backward from the final code. Search for
0x80004005, the decimal value2147467259, “failed,” and “return code.” Then move earlier in time until you find the first operation that failed. A later generic error is usually less useful than an earlier, specific message naming a file, command, share, driver, or disk action. - Translate a separate numeric code when appropriate. If the earlier entry contains a normal Windows error number, run
NET HELPMSG <number>from a command prompt to obtain the corresponding text. Use that translated message to investigate the earlier operation; do not treat the final0x80004005value as the root cause.
Keep the timestamp and task-sequence step together with every log entry you act on. This prevents a harmless warning from being mistaken for the event that stopped the deployment.
Choose the troubleshooting path from the failing step
| Where the deployment stops | First dependency to check | Evidence to seek |
|---|---|---|
| WinPE starts but cannot continue | Network adapter, storage driver, IP configuration, or deployment-share access | Missing adapter or disk, no IP address, share connection errors |
| Updating or rebuilding the deployment share | ADK and WIMGAPI compatibility | Unexpected WIMGAPI.DLL selected from the system PATH |
| A command, script, or application step | Command line, return code, permissions, and referenced files | “File not found,” access denied, malformed parameters, or a non-zero exit code |
| Apply Operating System or disk operations | WIM integrity, free space, partition layout, and firmware mode | Image-read errors, partition failures, or BIOS/UEFI mismatch |
| Windows 10 deployment with a specific MDT/ADK combination | Known BIOS/UEFI detection issue | MDT build 8456, Windows 10 ADK version 2004, and a BIOS machine identified as UEFI |
Restore WinPE network and storage access
If the first useful log entry concerns the deployment share, verify the WinPE environment before editing the task sequence. WinPE must contain a working driver for the machine’s network adapter and, when disk access is involved, the required storage controller. A deployment can reach the LiteTouch interface and still fail as soon as it needs to read content from the share or write to the target disk.

Outbyte Driver Updater FREEScan for outdated or missing drivers - takes under a minuteDriver Scan →Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →Check the adapter and IP address
- At the point of failure, open a command prompt in WinPE if your deployment configuration permits it.
- Confirm that the expected network adapter appears and that the machine has received an IP address. An absent adapter or an address that never arrives points to a missing or incompatible WinPE network driver, DHCP availability, or a network-path problem.
- Check that the deployment-share server can be reached from WinPE. A successful boot does not prove that the share is reachable; boot media can start locally while share access fails later.
- Verify the share path and credentials used by the deployment. Correct a typo, expired credential, or permission that prevents the account from reading the deployment files.
If the adapter or storage controller is missing, add the correct driver to the WinPE driver selection used by the deployment share, update the share, and regenerate the boot media. Test the newly generated media on the same hardware rather than assuming that changing the server-side driver list changed media already written to USB or other boot locations.
Check storage visibility
When logs show that disks cannot be enumerated or written, confirm that the storage device is visible in WinPE and that its controller driver is loaded. A network fix will not resolve a storage-driver failure, and a disk that is visible in firmware may still be unavailable to WinPE. Keep the firmware mode used to boot the media consistent with the partitioning plan in the task sequence.
Correct ADK and WIMGAPI mismatches
MDT uses components from the Windows Assessment and Deployment Kit (ADK). During deployment-share updates, verify that the WIMGAPI.DLL found first on the system PATH matches both the installed ADK build and the operating-system build. A different copy earlier in the PATH can be selected instead of the version you intended to use.
Verification procedure
- Record the ADK version installed on the MDT host and the Windows build being deployed.
- Inspect the PATH order and determine which
WIMGAPI.DLLwould be selected first. Check the file’s location and version information rather than relying only on its filename. - Remove or reorder conflicting PATH entries so the selected DLL belongs to the intended ADK and is compatible with the operating-system build.
- Restart the deployment-management tools, update the deployment share, and regenerate media after the correction.
- Review the update log again. If the same generic code remains, continue with the first concrete error in the new log rather than assuming the ADK change was the only dependency.
Do not copy a DLL from an unrelated computer or rename files to force a match. The relevant test is version and build compatibility, not merely whether a file with the expected name exists.
Audit the exact task-sequence command or script
When the log points to a command, script, package, or application step, inspect that step in isolation. A malformed command can end in the same LiteTouch return code as a network failure.
Items to verify
- Command line: Check executable names, quotation marks, switches, working directory, and whether paths contain spaces. Confirm that the command is valid in the environment where it runs, which may be WinPE rather than the full Windows installation.
- Return code handling: Identify the exit code produced by the command and the task-sequence setting that decides whether a non-zero code is fatal. Translate a specific Windows code with
NET HELPMSGwhen applicable. - Referenced files: Confirm that scripts, installers, configuration files, and packages are present in the deployment share or package source used by the step. A file available on the MDT server is not automatically available inside WinPE.
- Permissions: Check read and execute permissions for the account used during deployment. If the step accesses a second share, test that path separately from the primary deployment share.
- Architecture and context: Verify that a 32-bit or 64-bit executable is appropriate for the phase and that environment variables expected by the script actually exist.
For a complex sequence, make a copy of the task sequence and temporarily isolate the suspect step in a controlled test. Re-enable dependent steps one at a time after the command succeeds. This narrows the failure without permanently deleting production logic.
Validate the WIM, disk, and firmware state
When Apply Operating System fails
If the first meaningful error appears during Apply Operating System, validate the WIM source and the destination rather than focusing on the final LiteTouch code. Confirm that the referenced image is the intended WIM, that the deployment account can read it, and that the file is accessible from the deployment environment. Check available space on the destination and on any staging location used by the sequence.
A WIM-related failure can also follow a damaged or incomplete source, an incorrect image index, or a task-sequence reference that no longer matches the image in the deployment share. Re-select the intended image in the task sequence, update the share, and test with a known-good source when your change-control process allows it.

- Compare the task sequence’s partition layout with the machine’s firmware mode.
- Remove stale partitions only when the deployment policy permits data destruction; preserve user data when the sequence is intended to do so.
- Confirm that the target disk has enough free space and is writable.
- Check that the storage controller is visible in WinPE and that the expected disk is selected, especially on systems with multiple drives.
Do not switch a machine between BIOS and UEFI merely to suppress the message. Change the boot mode only when it matches the image, partition plan, and organization’s deployment standard.
Rank #4
Apply the documented BIOS/UEFI fix only for the matching case
Microsoft documents a specific Windows 10 failure involving MDT build 8456 used with Windows 10 ADK version 2004. In that combination, MDT can misidentify BIOS firmware as UEFI. The deployment may fail while applying the operating system and end with LiteTouch deployment failed, Return Code = 2147467259 0x80004005.
Conditions that must all match
- The MDT installation is build 8456.
- The Windows 10 ADK installed for that deployment is version 2004.
- The affected computer is using BIOS firmware, but the deployment behaves as though it is UEFI.
- The log places the failure around operating-system application or firmware-mode handling.
If those facts do not match, do not apply this package as a generic fix for every 0x80004005 occurrence. Continue investigating the concrete error identified in the logs.
Microsoft’s replacement procedure
- Close Deployment Workbench and any other MDT management process.
- Back up the existing
Microsoft.BDD.Utility.dllfiles before changing them. - Obtain the files supplied in
MDT_KB4564442. - Replace the affected x86 and x64 copies under the MDT Templates Distribution Tools directories with the updated files, preserving the backups separately.
- Reopen the tools, update or rebuild the deployment share, and regenerate deployment media. Media created before the toolkit files were replaced still contains the old components.
- Retest on a machine that exhibits the documented BIOS/UEFI conditions and compare the new log with the original failure.
Keep the backup until the deployment has passed validation. If the error remains after the replacement, return to the first concrete log entry; the package addresses this documented firmware-detection scenario, not unrelated scripts, shares, images, or drivers.

A successful test should show the previously failing step completing and the subsequent task-sequence actions starting normally. Check the deployment summary as well as the live log so that a later warning is not mistaken for a successful operating-system deployment.
Best Value
- Run the same hardware and boot-mode scenario used to reproduce the problem.
- Compare timestamps around the former failure point in
BDD.log,LiteTouch.log, orsmsts.log. - Confirm that the corrected dependency—share access, driver, DLL, command, image, disk action, or firmware detection—now produces the expected result.
- Retain the before-and-after logs and the change record, especially if the deployment share is used by multiple teams.
If a different step now fails, treat it as a new, specific problem. A changed error location often means the original blocker was removed and the sequence has advanced farther.
MDT’s retirement changes the long-term answer
Microsoft’s troubleshooting reference states: “Microsoft Deployment Toolkit (MDT) is now retired.” Microsoft recommends removing MDT task-sequence steps and MDT integration to help prevent task-sequence corruption and modification failures, and points organizations toward modern provisioning such as Windows Autopilot. Existing Configuration Manager operating-system deployment remains supported according to that reference.
That does not mean an existing deployment stops working immediately, nor does it replace the immediate troubleshooting above. It does mean that a permanent fix should include an inventory of MDT dependencies, a supported migration plan, and a test path for new provisioning workflows. Keep emergency repairs narrowly scoped, document any toolkit-file replacement, and avoid adding new reliance on retired MDT components.
Quick Recap
Practical recovery checklist
- Record the step immediately before the 0x80004005 message.
- Collect
BDD.log,LiteTouch.log,smsts.logwhen applicable, and the deployment summary. - Read backward to the first specific failure in CMTrace.
- Check WinPE network and storage drivers, IP assignment, and deployment-share access.
- Verify that the first
WIMGAPI.DLLon PATH matches the installed ADK and operating-system build. - Audit command lines, return codes, permissions, and referenced files at the exact failing step.
- Validate the WIM, image reference, free space, partition layout, and BIOS/UEFI mode.
- Use
MDT_KB4564442only for the documented MDT 8456 plus Windows 10 ADK 2004 BIOS/UEFI scenario. - Regenerate deployment media after changing toolkit files or the deployment share.
- Plan migration away from retired MDT integration while maintaining supported Configuration Manager OSD workflows.
