Hi Martín;

For instance, a kind of tool as Windows's scheduling agent.. The problem is that we don't know if the station will be using it (at a time that the program are running at a server)

No.. it needs to be done with no interference of any other tool (only the LAN's software)..

Today, (at client's facility) during the installation of our software (over the LAN), we have some steps to run in each machine that we install/upgrade our software.. This simple procedures is (nothing else) to record the hd's serial number and a password on each local hd.. In some facilities we have more than 20 stations installed..

So, for simpler than this can be, it still hard, if we multiply by 'N'..

We are trying to find a way on how to get the hd's serial number in each machine using API getvolumeinformation.. (no possibility to do that at a server. Because, getvolumeinformation only gets the information of local disks)

I was wondering, that we supposedly could run some kind of signal (at a server). And, now on, the others stations do their jobs (to record the hd's serial # by itself).



Thanks
