I am trying to Promote a new server to an existing domain using server 2016 but I keep getting an error message stating " The wizard cannot access the list of domains in the forest. The error is: The semaphore timeout period has expired."

Both machines are running windows server 2016. Netlogon and rpc are running on DC1. The new server is static, registered in the dns, pings, firewall/antivirus disabled, and is joined to the domain. Can anyone help me out?

Are you trying to do this over WiFi? Have you tested for a stable link? Generally you get this error when you're copying large files and the connection craps out. Bad NIC/NIC drivers/hardware in general?
