Hi, Andrew,
We have completed our investigation on Window clients implementation
regarding NETLOGON_NT_VERSION_5EX_WITH_IP bit. We confirmed that in all
clients of Windows NT 4 or higher, NETLOGON_NT_VERSION_5EX_WITH_IP bit of
NtVersion flag is always set for NetBIOS based mailslot ping, but is never
set for LDAP ping. We verified in our testing that clients did set this bit
when a NetBIOS domain name is used.
Please let us know if you have further questions.
Thanks !
Hongwei

Hi, Andrew,
Thanks for your question regarding NETLOGON_NT_VERSION_5EX_WITH_IP
flag.
In terms of the server, it is not deprecated. That is, current
servers still support requests that include this flag and respond
appropriately. For a server to be interoperable with Windows clients,
it needs to accept the flag in either way whenever it is sent. The
documentation explains what server should do if the bit is set in the
NtVersion flag and what server should do if it is not set and that it
should be prepared to accept a communication that contains this flag
at any time. Any actions taken by a Windows client based on this flag
do not affect the interoperability of a server implementation.
All those words, yet no new information!
Can you please answer the question: What windows client will set this flag,
and under what circumstances? If no Microsoft clients set this flag, then can
the documentation be updated to reflect this.
This is an important question for implementers. We could spend all year
implementing things that Microsoft servers do, but if we concentrate our
efforts on the things that exist the the real world, then we are all much more
productive.
Perhaps you could escalate this question to someone who is able to find this
out?
