It seems like you are experiencing an issue with updating the deployment share in MDT, specifically getting stuck on the "Copying WIM to the deployment share" step. This can be a frustrating problem, but there are several steps you can take to troubleshoot and resolve the issue.
Here are some steps you can follow:
Check Disk Space: Ensure that you have enough disk space available on the drive where your MDT deployment share is located. If the drive is running out of space, it can cause the update process to hang.
Log Files: MDT generates log files that can help you diagnose the issue. Look for the BDD.log file in the Logs folder of your Deployment Share. Open this log file using a text editor and look for any error messages or clues about what might be causing the problem.
Anti-Virus or Security Software: Sometimes, anti-virus or security software can interfere with the update process. Temporarily disable any such software and try updating the deployment share again.
Permissions: Ensure that the account you are using to update the deployment share has the necessary permissions. It should have full control over the deployment share folder.
Clean Boot: Try performing a clean boot of your system to rule out any conflicts with third-party software. This can help identify if a background process is causing the hang.
MDT Version: Make sure you are using the latest version of MDT. Sometimes, updating to the latest version can resolve known issues.
Check the Media Path: In the Deployment Share properties, check the Media Path under the General tab. Ensure it points to a valid and accessible location.
Check the Deployment Share Rules: Review your deployment share rules (customsettings.ini and bootstrap.ini) to ensure there are no errors or misconfigurations that might be causing the issue.
Recreate Deployment Share: As a last resort, you can try recreating the deployment share from scratch. This involves importing your operating systems, drivers, and applications again. Ensure you have backups of your configurations before doing this.
Remember to document any changes you make during troubleshooting and be cautious when making changes to your deployment share settings.
