How to enable and requirement for RC4 , NTLM v1 and SMB1 on Windows 2022 for legacy app and clients
Hi Active Directory migration from Windows Server 2012 R2 to Windows Server 2022, For applications or clients running on legacy operating systems such as Windows Server 2003, Windows Server 200...
You’re basically asking how to keep legacy clients and applications working after migrating AD to Windows Server 2022, including older authentication and encryption protocols such as NTLMv1, RC4, SMBv1, TLS 1.0/1.1, and unsigned LDAP. Because these protocols are insecure/deprecated, the safest approach is to identify which legacy systems actually require them and migrate or upgrade those dependencies rather than enabling everything globally.
