There is no one-size-fits-all answer to this question, as the answer will vary depending on the specific circumstances of your situation. However, in general, it is generally not recommended to reinstall DNS on a domain controller.
There are a few reasons for this. First, if the DNS server is compromised, the attacker may be able to intercept and modify DNS traffic on the domain controller. This could allow them to redirect or hijack domain traffic, or even take control of domain resources. Second, if the DNS server is not up to date, it may not be able to provide accurate and reliable DNS service.
Third, if the DNS server is replaced with a new one, it is important to ensure that the new server is configured properly and is compatible with the domain controller’s configuration. Finally, if the DNS server is replaced with a new one, it is also important to ensure that all of the domain controller’s associated application settings, such as Active Directory, are also updated to reflect the new server’s configuration.
Overall, it is generally recommended that users only replace DNS servers that are experiencing technical issues or are no longer being supported by the vendor. Replacing DNS servers on domain controllers is not typically recommended, as it can have unintended consequences.
