Comment 1 Andreas Schneider 2024-04-17 13:41:36 UTC 
I need to just check for the NETLOGON_NT_VERSION_5EX bit

        nt_version               : 0x00000015 (21)
               1: NETLOGON_NT_VERSION_1    
               0: NETLOGON_NT_VERSION_5    
               1: NETLOGON_NT_VERSION_5EX  
               0: NETLOGON_NT_VERSION_5EX_WITH_IP
               1: NETLOGON_NT_VERSION_WITH_CLOSEST_SITE
               0: NETLOGON_NT_VERSION_AVOID_NT4EMUL
               0: NETLOGON_NT_VERSION_PDC  
               0: NETLOGON_NT_VERSION_IP   
               0: NETLOGON_NT_VERSION_LOCAL
               0: NETLOGON_NT_VERSION_GC
