When it comes to restoring the system, you are able to use rollback points that were created previously. These snapshots are produced automatically, but only if the corresponding feature is enabled. Thanks to this, Windows generates the required files every time a major change is made to the system, installed updates, drivers and more.

Before effective troubleshooting of MDT can begin, you must have a clear understanding of the many .log files used during an operating system deployment. When you know which log files to research for what failure condition and at what time, issues that were once mysterious and difficult to understand may become clear and understandable.
BDD.log. This is the aggregated MDT log file that is copied to a network location at the end of the deployment if you specify the SLShare property in the Customsettings.ini file.
SMSTS.log. This file is created by the Task Sequencer and describes all Task Sequencer transactions. Depending on the deployment scenario, it may reside in %TEMP%, %WINDIR%\System32\ccm\logs, or C:\_SMSTaskSequence, or C:\SMSTSLog.
When running the Windows User State Migration Tool (USMT), MDT automatically adds the logging options to save the USMT log files to the MDT log file locations. The log files and when they are created are as follows:
The ZeroTouchInstallation.vbs script automatically scans the USMT progress log files for errors and warnings. The script generates event ID 41010 to Microsoft System Center Operations Manager with the following summary (where usmt_type is ESTIMATE, SCANSTATE, or LOADSTATE; error_count is the total number of errors found; and warning_count is the total number of warnings found):
Many error codes presented in the log files seem cryptic and difficult to correlate to an actual error condition. However, the following process demonstrates how to convert an error code and obtain meaningful information that may assist in problem resolution.
MDT creates log files that you can use to troubleshoot problems in the MDT deployment process. The following sections provide examples of how to use the MDT log files to troubleshoot the deployment process:
Problem: An error occurs while running a deployment that used a CustomSettings.ini file containing numerous sections and specifying, with the Priority property, the priority of each section to be processed. BDD.log contains the following error messages:
Possible Solution: The issue, as pointed out on the first line of the log file sample, is that permission to access the database was denied. Therefore, the script cannot establish a secure connection to the database, possibly because a user ID and password were not available. As a result, database access was attempted using the computer account. The easiest way to work around this issue is to grant everyone Read access to the database.
Possible Solution 1: Right-click the installation source file, and then click Properties. Click Unblock, and then click OK to remove the NTFS file system data streams from the file. Repeat this process for each installation source file that is blocked by the existence of one or more NTFS file system data streams.
Possible Solution 2: Use the Streams utility, as REF _Ref308173670 \h Figure 2 shows, to remove the NTFS file system data streams from the installation source file. The Streams utility can remove NTFS file system data streams from one or more files or folders at once.
Possible Solution: Implement the ZTICacheUtil.vbs script to enable download and execution for the installation. This script is designed to tweak the advertisement to enable download and execute. The download uses Background Intelligent Transfer Service (BITS) if the Configuration Manager distribution point is Web-based Distributed Authoring and Versioning and BITS enabled. At the same time, it modifies Configuration Manager to run the ZTICache.vbs script first, which makes sure the program does not delete itself during the deployment process.
Possible Solution 1: Relocate the MSP file to the Updates directory, and then run setup.exe without specifying the /adminfile option. For more information about deploying updates during the installation, see Deploying the 2007 Office system.
Possible Solution 2: Verify that the MSP file does not have the Suppress modal check box selected. For more information about configuring this setting, see Overview of 2007 Office System Deployment.
Possible Solution: Be sure that the WIM file does not include a MININT or _SMSTaskSequence folder. To delete these folders, first use the ImageX utility to mount the WIM file, and then delete the folders.
If an Access Denied error occurs when you attempt to delete the folders from the WIM file, open a Command Prompt window, switch to the root of the image contained in the WIM file, and then run RD MININT and RD _SMSTaskSequence.
Problem: If you use the ZTIWindowsUpdate.wsf script to apply software updates during deployment, note that this script may communicate directly with the Microsoft Update website to download and install the required Windows Update Agent binaries, scan for applicable software updates, download the binaries for the applicable software updates, and then install the downloaded binaries. This process requires that your networking infrastructure be configured to allow the target computer to gain access to the Microsoft Update website.
If the deployment share does not contain the Windows Update Agent installation files and the target computer does not have appropriate Internet access, error "wuredist.cab not found" is reported in the ZTIWindowsUpdate.log and BDD.log files.
On a 64-bit operating system, MDT always uses the x64 WIMGAPI.DLL file; only that file should be in the system PATH. On a 32-bit operating system, MDT always uses the x86 WIMGAPI.DLL file; only that file should be in the system PATH. (Other products, such as Configuration Manager, use the 32-bit version of WIMGAPI.DLL, even on a 64-bit operating system, but they manage and install that version.)
Possible Solution: To properly skip a wizard page, include all properties that would be specified on that wizard page where appropriate in the MDT DB or CustomSettings.ini file along with appropriate values. If a property is configured improperly for a skipped wizard page, that page will be shown. For more information about which properties are required to ensure that a wizard page is skipped, see the section, "Providing Properties for Skipped Deployment Wizard Pages", in the MDT document Toolkit Reference.
Possible Solution: Specify the locale in the UILanguage property. In ZTI and UDI, the ZTIBde.wsf script runs in the system control, so a full user profile is not loaded. When the ZTIBde.wsf script tries to read the locale information it is not in the registry, because the registry (user profile) is not fully loaded. As a workaround, specify the locale in the UILanguage property.
Possible Solution: Override the default setting on the Specify the BitLocker recovery details page in the Windows Deployment Wizard. The Windows Deployment Wizard summary page displays a warning to inform the user which drive letter was selected to store BitLocker recovery information. In addition, the BDD.log and ZTIBDE.log files record the removable media devices detected and which device was selected to store the BitLocker recovery information.
Problem: Not enough unallocated disk space exists on the target computer to enable BitLocker. To deploy BitLocker on a target computer, at least 2 gigabytes (GB) of unallocated disk space is required to create the system volume. The system volume is the volume that contains the hardware-specific files needed to load Windows after the BIOS has booted the computer.
The white paper Troubleshooting Device Installation with the SetupAPI Log File provides information about debugging Windows device installation. Specifically, the paper provides guidelines for driver developers and testers to interpret the SetupAPI log file.
One of the most useful log files for debugging purposes is the SetupAPI.log file. This plain-text file maintains the information that SetupAPI records about device installation, service pack installation, and update installation. Specifically, the file maintains a record of device and driver changes as well as major system changes beginning from the most recent Windows installation. This paper focuses on using the SetupAPI log file to troubleshoot device installation; it does not describe the log file sections that are associated with service pack and update installations.
In brief, the PXE protocol operates as follows: The client computer initiates the protocol by broadcasting a DHCP Discover packet containing an extension that identifies the request as coming from a client computer that implements the PXE protocol. Assuming that a boot server implementing this extended protocol is available, the boot server sends an offer containing the IP address of the server that will service the client. The client uses Trivial File Transfer Protocol to download the executable file from the boot server. Finally, the client computer runs the downloaded bootstrap program.
The initial phase of this protocol piggybacks on a subset of the DHCP messages to enable the client to discover a boot server (that is, a server that delivers executable files for new computer setup). The client computer may use the opportunity to obtain an IP address (which is the expected behavior) but is not required to do so.
Is the IP address for the Windows Deployment Services server in the IP Helper file on the router through which the connection is made? If the list of IP addresses in the IP Helper file is long, can you move the address for the Windows Deployment Services server near the top 2ff7e9595c
