Hi,
I use Windows Server 2019 DC in my environment. All updates are installed. We use Windows 10/11 clients. We use a mix of 2012R2 - 2022 OS on other servers.
I will disable WDigest Authentication in the Default Domain Controller policy as follows.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\WDigest “UseLogonCredential” REG_DWORD 0
Could this have any negative effect on the system?
