Sorry for the wrong copy-paste.
On the server I scanned; both plugins told that the server is vulnerable. 
ms06-035 AND ms06-040

Vulnerability   microsoft-ds (445/tcp) 
Synopsis :

Arbitrary code can be executed on the remote host due to a flaw in the

The remote host is vulnerable to heap overflow in the 'Server' service 
which
may allow an attacker to execute arbitrary code on the remote host with

In addition to this, the remote host is also vulnerable to an information
disclosure vulnerability in SMB which may allow an attacker to obtain
portions of the memory of the remote host.

And I ran both plugins through nasl : Both ended with "not vulnerable" 
diagnostic.
I suppose that it's due to the fact that the OS is not recognized when the 
plugin is launched in standalone :

..........................
[15071]() NASL> [002bc6b8] <- "Host/OS/smb"
[15071](/tools/nessus/lib/nessus/plugins/smb_kb917159.nasl) NASL> Call 
get_kb_item(1: "Host/OS/smb")
[15071](/tools/nessus/lib/nessus/plugins/smb_kb917159.nasl) NASL> Return 
get_kb_item: NULL
[15071]() NASL> [002bdac0] <- undef
NASL:0159> if ("Windows" >!< os) { ... } 
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
[15071](/tools/nessus/lib/nessus/plugins/smb_kb917159.nasl) NASL> 
[002bdac0] -> undef
NASL:0157> exit(...)
[15071]() NASL> [002bc6b8] <- 0
[15071](/tools/nessus/lib/nessus/plugins/smb_kb917159.nasl) NASL> Call 
exit(1: 0)
[15071](/tools/nessus/lib/nessus/plugins/smb_kb917159.nasl) NASL> Return 
exit: 0

Is there a way to force the plugin to check the vuln anyway.
I have to do this because it seems that it is a false positive, and I want 
to check ( and eventually show to the admins ) 
the data exchanged between nessus and the server.
