We have some legacy software on Windows 2003 server unable to go higher.
Made a share on 2070 cluster with local user access to it and all anonimous blocked.
When windows 10 / 2019 tries get in - no problems. Security logs get NTLMv2 auth.
With Windows 2003, logs show guest authentication attempt that fails.
When I try to get in parent \\10.10.10.10\ - authentication goes as planned with local netApp credentials.
<Data Name="TargetUserIsLocal">true</Data>
<Data Name="TargetDomainName">5NETAPP-SVMSH</Data>
<Data Name="AuthenticationPackageName">NTLM_V2</Data>
After that on clicking a folder and etnering credentials - error on "wrong password\user" and guest attemts in log.
