SCCM - MDT - DNS issues at Site but cant find log to show this

Hi Reddit folks!

I've got a task sequence created in MDT with UDI. My task sequence was working fine for weeks and all of a sudden, it stopped joining machines to the domain and of course not installing any apps...

I've noticed a few computers are having trust relationship issues as well which can be related to DNS.

What i want to do is try to find the log that shows the attempt to join the computer to the domain and it fail which i can definitively show the Network team that DNS is not working correctly at this site while XYZ other site is working fine.

Thanks in advance for your help and time!
