Client can ping to AD Server by IP Address & Host name, but cannot join domain

[nyda_blog]

Dear  IT Pro,

I installed and configured AD server 2019 on Hyper-V and installed Window7 as a client for testing in my environment. I have installed & configured AD DS and DNS and after verifying it looked working well. and then I did configure network interface same as my server and tried to ping both IP & Hostname are work. anyway I also nslookup on my client and it looks resolved, but once I join the domain I got an error that my "error 0x000007B ERROR_INVALID_NAME "I need help to advise me to fix this issue. Thank you!
