Subject: [MS-SMB2:2.2.1.x] SYNC vs. ASYNC commands.

Dear Dochelp:

In [MS-SMB2], sections 2.2.1.1 and 2.2.1.2 both describe the Command field in the SMB2 header, and both give a complete list of all SMB2 commands.

Reading section 2.2.1, however, it seems that only the SMB2_CANCEL command uses the ASYNC header format, and that all others use the SYNC format.  If that interpretation is correct, then...

* In section 2.2.1.1, only SMB2_CANCEL should be listed as a valid command
   for the Command field.

* In section 2.2.1.2, SMB2_CANCEL should be excluded from the list of
   valid SYNC-format requests.

* Section 2.2.30 should indicate that the ASYNC header should be used
   instead of the SYNC header.

Am I misinterpreting the information in 2.2.1?  Please clarify the circumstances under which the ASYNC header format is used, vs. the SYNC format.

Thanks.

Chris -)-----
