RE: SNMP vulnerability test?

[Jason Craig <craig () agdean ucdavis edu>]

M$ is full of crap on this one...

We don't use SNMP for anything, and we're finding it randomly enabled on a
number of workstations and nearly all win2k servers.  We are running
locked-down IIS and OWA, and for whatever reason, these services turn on
SNMP.  However, turning it off doesn't seem to hamper them.  So, the obvious
logical question ensues: why do IIS and OWA (and possibly just win2k server)
enable SNMP while not requiring SNMP to function properly?  Additionally,
why do some installs of wkstn enable SNMP while others do not?  I can verify
nearly all of these instances as I am the one doing the installs (and yes,
personal web server was never installed).

How did it get turned on?  Microsoft said in the CERT advisory:

     Summary:
     All  Microsoft  implementations  of  SNMP  v1  are  affected by the
     vulnerability.  The  SNMP v1 service is not installed or running by
     default on any version of Windows. A patch is underway to eliminate
     the  vulnerability.  In  the  meantime,  we recommend that affected
     customers disable the SNMP v1 service.

Is this like the "W2K doesn't install IIS, but if you upgraded a machine
that had Personal Webpage (or whatever it was) it will upgrade that to IIS"?
