|
|
Attempts to grab the server's statistics over SMB and MSRPC, which uses TCP
|
|
ports 445 or 139.
|
|
|
|
An administrator account is required to pull these statistics on most versions
|
|
of Windows, and Vista and above require UAC to be turned down.
|
|
|
|
Some of the numbers returned here don't feel right to me, but they're definitely
|
|
the numbers that Windows returns. Take the values here with a grain of salt.
|
|
|
|
These statistics are found using a single call to a SRVSVC function,
|
|
<code>NetServerGetStatistics</code>. This packet is parsed incorrectly by Wireshark,
|
|
up to version 1.0.3 (and possibly higher).
