Text from email:

"ood morning Matthieu. Thanks for your patience. Our documentation team has 
responded to 3 of the four cross-reference requests. Details are shown below, 
as well as an attached pdf ([MS-ADTS]_Changes.pdf) showing new text for that 
document.

1. A request was made for a link in '[MS-ADTS] section 7.1.6.7.3 
msDs-supportedEncryptionTypes', pointing to '[MS-LSAD] section 2.2.7.18 
TRUSTED_DOMAIN_SUPPORTED_ENCRYPTION_TYPES'.

We haven't added this link because the relationship between the 
trustedDomain!msDs-supportedEncryptionTypes attribute and 
TRUSTED_DOMAIN_SUPPORTED_ENCRYPTION_TYPES structure is already specified in 
'[MS-LSAD] section 3.1.1.5 Trusted Domain Object Data Model'.

2. A request was made for a link in '[MS-ADTS] section 7.1.6.7.3 
msDs-supportedEncryptionTypes', pointing to '[MS-NRPC] section 2.2.1.3.11 
NETLOGON_DOMAIN_INFO (SupportedEncTypes)'.

We haven't added this link, because we think this link would be inappropriate, 
since these two sections are about two different types of object. '[MS-ADTS] 
section 7.1.6.7.3 msDs-supportedEncryptionTypes' is about trustedDomain 
objects; however, the NETLOGON_DOMAIN_INFO structure in '[MS-NRPC] section 
2.2.1.3.11 NETLOGON_DOMAIN_INFO' provides information on a domain joined 
computer object.

Therefore, instead of adding a cross reference between 
trustedDomain!msDs-supportedEncryptionTypes and NETLOGON_DOMAIN_INFO, we have 
added text in the [MS-ADTS] sections noted below providing information on the 
msDs-supportedEncryptionTypes attribute of the computer object.

[MS-ADTS] 7.4.1 State of a Machine Joined to a Domain
[MS-ADTS] 7.4.2 State in an Active Directory Domain
[MS-ADTS] 7.4.3 Relationship to Protocols

3. A request was made for links in '[MS-LSAD] section 2.2.7.18 
TRUSTED_DOMAIN_SUPPORTED_ENCRYPTION_TYPES', pointing to '[MS-ADTS] 7.1.6.7.3 
msDs-supportedEncryptionTypes' and '[MS-NRPC] 2.2.1.3.11 NETLOGON_DOMAIN_INFO' 
(SupportedEncTypes).

We haven't added these links, because when describing the member 
SupportedEncTypes of struct NETLOGON_DOMAIN_INFO, '[MS-NRPC] section 2.2.1.3.11 
NETLOGON_DOMAIN_INFO' links to section '[MS-LSAD] 2.2.7.18 
TRUSTED_DOMAIN_SUPPORTED_ENCRYPTION_TYPES', which describes the structure 
represented in SupportedEncTypes. Additionally '[MS-LSAD] section 3.1.1.5 
Trusted Domain Object Data Model' references '[MS-ADTS] section 7.1.6.7.3 
msDs-supportedEncryptionTypes' to link the data retrieved from AD.

Also, [MS-LSAD] does not need to reference [MS-NRPC] for the purposes of 
supported encryption types because MS-LSAD does not consume any encryption type 
definition in [MS-NRPC].

Additionally, [MS-LSAD] supportedEncryptionTypes usage is for trusts only, 
whereas [MS-NRPC] supportedEncryptionTypes usage is for both trusts and 
computers.

4. A request was made for links in '[MS-NRPC] 2.2.1.3.11 NETLOGON_DOMAIN_INFO 
(SupportedEncTypes)', pointing to '[MS-ADTS] 7.1.6.7.3 
msDs-supportedEncryptionTypes'.

This request is currently pending review."

Hello  Matthieu.
    The Microsoft Escalation Engineer that you have been working with, Bill 
Wesse,  is out of our office. I will be handling this case in his absence. 
Unfortunately I have not been privy to all of the email exchanges regarding 
this case. I want to make sure that we address all of your outstanding 
questions in this regard. To my understanding you have one remaining question 
in this area which is:  The very first time the SupportedEncTypes is returned, 
if the DC has no information about the workstation, what should be returned? 
0x00 or 0xFF or something else.

Is it accurate that this is the only remaining question regarding this case?
I think so but I must confess that my question was asked already some times ago 
and as you broke the thread I have some difficulties to remember it in all the 
details.



Matthieu.
