Andrew,
I just want to make sure that you have received all the information for this
request. As Bill already indicated, how the OS version specified in
NETLOGON_WORKSTATION_INFO is translated into the operatingSystemVersion
attribute is documented in 2.2.1.3.16 of MS-NRPC
http://msdn.microsoft.com/en-us/library/dd240432.aspx as follows:
OsVersionInfo: If not NULL, the attribute operatingSystemVersion on the
client's computer account in Active Directory (using the ABNF Syntax as
specified in [RFC2234]) is set to:
If OsVersionInfo.dwBuildNumber is 0:
operatingSystemVersion = MajorVersion "." MinorVersion
MajorVersion = OsVersionInfo.dwMajorVersion
MinorVersion = OsVersionInfo.dwMinorVersionOtherwise:
operatingSystemVersion = MajorVersion "." MinorVersion
"."
BuildNumber
MajorVersion = OsVersionInfo.dwMajorVersion
MinorVersion = OsVersionInfo.dwMinorVersion
BuildNumber = OsVersionInfo.dwBuildNumber
We will add the reference to this information to OsVersion in 2.2.1.3.6
NETLOGON_WORKSTATION_INFO in the future version of the document.
Please let us know if you have any further questions.
Thanks!
Hongwei

Andrew - thanks for focusing me - I assume you are referring to the quoted text
below:
OsVersion: ... "The DC that receives this data structure updates the
operatingSystemVersion attribute of the client's machine account object in
Active Directory with this value, unchanged and uninterpreted, as specified in
[MS-ADTS]."
I find that OSVERSIONINFOEX is equivalent to NL_OSVERSIONINFO_V1, which is
documented as shown below - and contains the information you are seeking.
I have already advised the bug/TDI owner concerning this.

No, it is the removal of the explanation of how the OS version specified here
is translated into the operatingSystemVersion attribute, and how/when that is
done that seems to have been removed.
