<p class=MsoNormal>Hi,<o:p></o:p></p>
<p class=MsoNormal>I have a curious problem. I use Tim Golden’s module for WMI,
and I use the ‘StdRegProv’ to query a remote registry over WMI. I get an
unusual network load for this procedure.<o:p></o:p></p>
<p class=MsoNormal>Using a packet capture, I saw that each new query contains all
the previous ones. <o:p></o:p></p>
<p class=MsoNormal>Do I use the module in a wrong way?<o:p></o:p></p>
<p class=MsoNormal>Did anyone else encounter this problem?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
