It is easy, in the docs, to document actual protocol changes between NT and
W2K+ systems. Changes to the protocol can and should be documented in [MS-SMB].
Unfortunately, it is not nearly as easy to document changes to non-protocol
Windows Behavior. All WBNs really need a to be referenced from within the
specification.
You can't, for instance, talk about the change from 45 to 60 seconds between
W-NT4 and W2K in [MS-CIFS] because [MS-CIFS] specifically covers NT3.51 and
NT4 clients/servers, and W98 clients. You also can't talk about it in
[MS-SMB] because there is no actual protocol change.
The best I could suggest is to add a line somewhere in section 3 of [MS-SMB]
that says:
Client.SessionTimeoutValue is as defined in [MS-CIFS], section ??? <WBN>.
<WBN>: In Windows 2000, Windows 2003, Windows XP, Windows Vista,
Windows 7, Windows 2008, and Windows 2008 R2 (have I missed
any?), the default Client.SessionTimeoutValue is 60 seconds.
...and then reference both the KB article and the section of [MS-CIFS] that
provides the WBN that states that the timeout is 45 seconds.
