Hello,
Thank you for posting in Q&A forum.
Here's some basic steps we can try:
- Check if "Join domain" option is configured well in Task Sequence Configuration.
- Check network connection to DC:
Run ping and nslookup command in CMD windows on MDT server to check network connectivity to the domain controller. Sometimes DNS resolution can also lead to this issue.
Let's see if it can help narrow down the issue.
Best Regards,
Shujun
