Doc Text:
* when establishing connections with NETLOGON, Samba uses the Active Directory netlogon negotiate flags even outside of Active Directory environments. This avoids machines running Windows Server 2008 from incorrectly identifying the connection attempt as a downgrade attack. However, these same flags would prevent a successful connection with machines running Windows NT. Therefore, if attempts to make a connection fail while the Active Directory netlogon negotiate flags are set, Samba will try again without the flags in place so that successful connections with machines running Windows NT are possible.
