Hello, Thank you for posting in Q&A forum. Yes, it could impact the DNS resolution in some way. It's more recommended to implement a split DNS configuration where you have separate DNS servers for internal and external resolution of the same domain. Or you can also consider creating a subdomain for your internal resources. Proper DNS resolution can bring less AD authentication or LDAP issue. Best Regards,
