unable to look up Servername

[LotharDegen]

Hi all,

strugling with an odd Problem here


I do run a Windows 2019 Server with AD and DNS configured. Servername is properly configured in DNS and can be pinged from another device, but not resolved.


As a result I cannot join the device to the domain.

Domain exists, server has a proper A Entry in DNS.

When trying a domain join, NetSetup.log shows the following result:
