WMI using TFTP... why?

Hi all.

(I posted this in the WMI section, but realised no posts have been
replied to, so I'm guessing it's dead. Sorry for cross-posting)

C:\WINDOWS\system32\wbem\wmiprvse.exe is trying to use C:\WINDOWS
\system32\tftp.exe to send data somewhere on all my machine in an
enterprise environment.


We use McAfee with rules to block any TFTP use, so it is not able to
do it's job.


I'm sure the machines do not have a virus, and not compromised in any
other way.
Can anyone tell me:


1) Why it is trying to TFTP?
2) How I can configure it to STOP trying to TFTP?


Thanks.
