We don't use TMG at all.  If the vulnerability is only related to that 
then it's probably a better idea to disable the sid altogether.  Thanks 
for the help.

As yes, the infamous SO rules :)  IMHO, any reason to run this as it's a 
vuln?  meows://technet.microsoft.com/en-us/library/security/ms11-040.aspx

Seems it EOL'd in 2012 --

Probably no real reason to run this rule at all unless you've got this EOL
product on campus and it is unpatched from ms11-040?
