He said he wanted to check for modems from the LAN side of the house
rather than from the telco side.
One of the things we were looking at some time back was using WMI to check
for modems installed on remote windoze systems. we had no problems finding
modems using WMI, there were plenty. The challenge we ran into was
finding which of the installed modems were actually getting a dial tone.
If your management wants you to go ahead and disable all of the modems you
find then I suppose that finding a dial tone doesn't really matter. Of
course that was not the case for us.
We couldnt figure out how to remotely detect a dial tone so we wound up
going to all the PBX's instead and pulling all the DID's and ranges.
Then we did what kevin said to do. We used phonesweep.
Fortuntately phonesweep has an API that you can use to automate the sweeps
as well as update the numbers in the phonesweep databases.
Maybe someone on the list has some info on approaching this from the LAN
side. I'd be interested to hear if anyone has a way to connect to a
remote workstation over the LAN and check to see if the installed modem
has a dial tone.
